[jira] [Updated] (SPARK-26960) Reduce flakiness of Spark ML Listener test suite by waiting for listener bus to clear
[

Joseph K. Bradley updated SPARK-26960:

Description:
[SPARK-23674] added SparkListeners for some spark.ml events, as well as a test
suite. I've observed flakiness in the test suite (though I unfortunately only
have local logs for failures, not permalinks). Looking at logs, here's my
assessment, which I confirmed with [~zsxwing].
Test failure I saw:
{code}
[info] - pipeline read/write events *** FAILED *** (10 seconds, 253
milliseconds)
[info] The code passed to eventually never returned normally. Attempted 20
times over 10.01409 seconds. Last failure message: Unexpected event thrown:
SaveInstanceEnd(org.apache.spark.ml.util.DefaultParamsWriter@6daf89c2,/home/jenkins/workspace/mllib/target/tmp/spark-572952d8-5d2d-4a6c-bd4f-940bb0bbc3d5/pipeline/stages/0_writableStage).

URL: https://issues.apache.org/jira/browse/SPARK-26960
Project: Spark
Issue Type: Improvement
Components: ML, Tests
Affects Versions: 3.0.0
Reporter: Joseph K. Bradley
Assignee: Joseph K. Bradley
[SPARK-23674] added SparkListeners for some spark.ml events, as well as a test
suite. I've observed flakiness in the test suite (though I unfortunately only
have local logs for failures, not permalinks). Looking at logs, here's my
assessment, which I confirmed with [~zsxwing].
Test failure I saw:
{code}
[info] - pipeline read/write events *** FAILED *** (10 seconds, 253
milliseconds)
[info] The code passed to eventually never returned normally. Attempted 20
times over 10.01409 seconds. Last failure message: Unexpected event thrown:
SaveInstanceEnd(org.apache.spark.ml.util.DefaultParamsWriter@6daf89c2,/home/jenkins/workspace/mllib/target/tmp/spark-572952d8-5d2d-4a6c-bd4f-940bb0bbc3d5/pipeline/stages/0_writableStage).

> GraphX was one of the foundational pillars of the Spark project, and is the
> current graph component. This reflects the importance of the graphs data
> model, which naturally pairs with an important class of analytic function,
> the network or graph algorithm.
> However, GraphX is not actively maintained. It is based on RDDs, and cannot
> exploit Spark 2’s Catalyst query engine. GraphX is only available to Scala
> users.
> GraphFrames is a Spark package, which implements DataFrame-based graph
> algorithms, and also incorporates simple graph pattern matching with fixed
> length patterns (called “motifs”). GraphFrames is based on DataFrames, but
> has a semantically weak graph data model (based on untyped edges and
> vertices). The motif pattern matching facility is very limited by comparison
> with the well-established Cypher language.
> The Property Graph data model has become quite widespread in recent years,
> and is the primary focus of commercial graph data management and of graph
> data research, both for on-premises and cloud data management. Many users of
> transactional graph databases also wish to work with immutable graphs in
> Spark.
> The idea is to define a Cypher-compatible Property Graph type based on
> DataFrames; to replace GraphFrames querying with Cypher; to reimplement
> GraphX/GraphFrames algos on the PropertyGraph type.
> To achieve this goal, a core subset of Cypher for Apache Spark (CAPS),
> reusing existing proven designs and code, will be employed in Spark 3.0. This
> graph query processor, like CAPS, will overlay and drive the SparkSQL
> Catalyst query engine, using the CAPS graph query planner.

> Check Java compatibility for this release:
> * APIs in {{spark.ml}}
> * New APIs in {{spark.mllib}} (There should be few, if any.)
> Checking compatibility means:
> * Checking for differences in how Scala and Java handle types. Some items to
> look out for are:
> ** Check for generic "Object" types where Java cannot understand complex
> Scala types.
> *** *Note*: The Java docs do not always match the bytecode. If you find a
> problem, please verify it using {{javap}}.
> ** Check Scala objects (especially with nesting!) carefully. These may not
> be understood in Java, or they may be accessible only via the weirdly named
> Java types (with "$" or "#") which are generated by the Scala compiler.
> ** Check for uses of Scala and Java enumerations, which can show up oddly in
> the other language's doc. (In {{spark.ml}}, we have largely tried to avoid
> using enumerations, and have instead favored plain strings.)
> * Check for differences in generated Scala vs Java docs. E.g., one past
> issue was that Javadocs did not respect Scala's package private modifier.
> If you find issues, please comment here, or for larger items, create separate
> JIRAs and link here as "requires".
> * Remember that we should not break APIs from previous releases. If you find
> a problem, check if it was introduced in this Spark release (in which case we
> can fix it) or in a previous one (in which case we can create a java-friendly
> version of the API).
> * If needed for complex issues, create small Java unit tests which execute
> each method. (Algorithmic correctness can be checked in Scala.)
> Recommendations for how to complete this task:
> * There are not great tools. In the past, this task has been done by:
> ** Generating API docs
> ** Building JAR and outputting the Java class signatures for MLlib
> ** Manually inspecting and searching the docs and class signatures for issues
> * If you do have ideas for better tooling, please say so we can make this
> task easier in the future!

Summary: SparkSession.conf fails when given default value with
Python 3
Key: SPARK-25397
URL: https://issues.apache.org/jira/browse/SPARK-25397
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.3.1
Reporter: Joseph K. Bradley
Spark 2.3.1 has a Python 3 incompatibility when requesting a Conf value from
SparkSession when you give non-string default values. Reproduce via
SparkSession call:
{{spark.conf.get("myConf", False)}}
This gives the error:
{code}
>>> spark.conf.get("myConf", False)
Traceback (most recent call last):
File "", line 1, in
File
"/Users/josephkb/work/spark-bin/spark-2.3.1-bin-hadoop2.7/python/pyspark/sql/conf.py",

line 62, in _checkType
if not isinstance(obj, str) and not isinstance(obj, unicode):
*NameError: name 'unicode' is not defined*
{code}
The offending line in Spark in branch-2.3 is:
https://github.com/apache/spark/blob/branch-2.3/python/pyspark/sql/conf.py
which uses the value {{unicode}} which is not available in Python 3.

That's a good point. Let's do it your way. : )
You're right that putting this knowledge of wrapper classpaths on the Python
side is better organized. That will allow users to wrap Scala classes later
without breaking APIs (by adding new mix-ins).

Description:
This is a follow-up for [SPARK-17025], which allowed users to implement Python
PipelineStages in 3rd-party libraries, include them in Pipelines, and use
Pipeline persistence. This task is to make it easier for 3rd-party libraries
to have PipelineStages written in Java and then to use pyspark.ml abstractions
to create wrappers around those Java classes. This is currently possible,
except that users hit bugs around persistence.
I spent a bit thinking about this and wrote up thoughts and a proposal in the
doc linked below. Summary of proposal:
Require that 3rd-party libraries with Java classes with Python wrappers
implement a trait which provides the corresponding Python classpath in some
field:
{code}
trait PythonWrappable {
def pythonClassPath: String = …
}
MyJavaType extends PythonWrappable
{code}
This will not be required for MLlib wrappers, which we can handle specially.
One issue for this task will be that we may have trouble writing unit tests.
They would ideally test a Java class + Python wrapper class pair sitting
outside of pyspark.

Some fixes we'll need include:
* an overridable method for converting between Python and Java classpaths. See
https://github.com/apache/spark/blob/b56e9c613fb345472da3db1a567ee129621f6bf3/python/pyspark/ml/util.py#L284

One unusual thing for this task will be to write unit tests which test a custom
PipelineStage written outside of the pyspark package.

[jira] [Updated] (SPARK-12878) Dataframe fails with nested User Defined Types
[

Joseph K. Bradley updated SPARK-12878:

Description:
Spark 1.6.0 crashes when using nested User Defined Types in a Dataframe.
In version 1.5.2 the code below worked just fine:
{code}
import org.apache.spark.{SparkConf, SparkContext}
import org.apache.spark.sql.catalyst.InternalRow
import org.apache.spark.sql.catalyst.expressions.GenericMutableRow
import org.apache.spark.sql.types._
@SQLUserDefinedType(udt = classOf[AUDT])
case class A(list:Seq[B])
class AUDT extends UserDefinedType[A] {
override def sqlType: DataType = StructType(Seq(StructField("list",
ArrayType(BUDT, containsNull = false), nullable = true)))
override def userClass: Class[A] = classOf[A]
override def serialize(obj: Any): Any = obj match {
case A(list) =>
val row = new GenericMutableRow(1)
row.update(0, new GenericArrayData(list.map(_.asInstanceOf[Any]).toArray))
row
}
override def deserialize(datum: Any): A = {
datum match {
case row: InternalRow => new A(row.getArray(0).toArray(BUDT).toSeq)
}
}
}
object AUDT extends AUDT
@SQLUserDefinedType(udt = classOf[BUDT])
case class B(text:Int)
class BUDT extends UserDefinedType[B] {
override def sqlType: DataType = StructType(Seq(StructField("num",
IntegerType, nullable = false)))
override def userClass: Class[B] = classOf[B]
override def serialize(obj: Any): Any = obj match {
case B(text) =>
val row = new GenericMutableRow(1)
row.setInt(0, text)
row
}
override def deserialize(datum: Any): B = {
datum match { case row: InternalRow => new B(row.getInt(0)) }
}
}
object BUDT extends BUDT
object Test {
def main(args:Array[String]) = {
val col = Seq(new A(Seq(new B(1), new B(2))),
new A(Seq(new B(3), new B(4
val sc = new SparkContext(new
SparkConf().setMaster("local[1]").setAppName("TestSpark"))
val sqlContext = new org.apache.spark.sql.SQLContext(sc)
import sqlContext.implicits._
val df = sc.parallelize(1 to 2 zip col).toDF("id","b")
df.select("b").show()
df.collect().foreach(println)
}
}
{code}
In the new version (1.6.0) I needed to include the following import:
`import org.apache.spark.sql.catalyst.expressions.GenericMutableRow`
However, Spark crashes in runtime:
{code}

[jira] [Created] (SPARK-24632) Allow 3rd-party libraries to use pyspark.ml abstractions for Java wrappers for persistence
Joseph K. Bradley created SPARK-24632: - Summary: Allow 3rd-party libraries to use pyspark.ml abstractions for Java wrappers for persistence Key: SPARK-24632 URL: https://issues.apache.org/jira/browse/SPARK-24632 Project: Spark Issue Type: Improvement Components: ML, PySpark Affects Versions: 2.4.0 Reporter: Joseph K. Bradley This is a follow-up for [SPARK-17025], which allowed users to implement Python PipelineStages in 3rd-party libraries, include them in Pipelines, and use Pipeline persistence. This task is to make it easier for 3rd-party libraries to have PipelineStages written in Java and then to use pyspark.ml abstractions to create wrappers around those Java classes. This is currently possible, except that users hit bugs around persistence. One fix we'll need is an overridable method for converting between Python and Java classpaths. See https://github.com/apache/spark/blob/b56e9c613fb345472da3db1a567ee129621f6bf3/python/pyspark/ml/util.py#L284 One unusual thing for this task will be to write unit tests which test a custom PipelineStage written outside of the pyspark package. -- This message was sent by Atlassian JIRA (v7.6.3#76005) - To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
[jira] [Commented] (SPARK-17025) Cannot persist PySpark ML Pipeline model that includes custom Transformer

Joseph K. Bradley commented on SPARK-17025:
---
We've tested it with Python-only implementations, and it works. You end up
hitting problems if you use the (sort of private) Python abstractions for Java
wrappers like JavaMLWritable. I'll create a follow-up issue for that and close
this one as fixed.

> h1. Background and motivation
> SparkR supports calling MLlib functionality with an [R-friendly
> API|https://docs.google.com/document/d/10NZNSEurN2EdWM31uFYsgayIPfCFHiuIu3pCWrUmP_c/].
> Since Spark 1.5 the (new) SparkML API which is based on [pipelines and
> parameters|https://docs.google.com/document/d/1rVwXRjWKfIb-7PI6b86ipytwbUH7irSNLF1_6dLmh8o]
> has matured significantly. It allows users build and maintain complicated
> machine learning pipelines. A lot of this functionality is difficult to
> expose using the simple formula-based API in SparkR.
> We propose a new R package, _SparkML_, to be distributed along with SparkR as
> part of Apache Spark. This new package will be built on top of SparkR’s APIs
> to expose SparkML’s pipeline APIs and functionality.
> *Why not SparkR?*
> SparkR package contains ~300 functions. Many of these shadow functions in
> base and other popular CRAN packages. We think adding more functions to
> SparkR will degrade usability and make maintenance harder.
> *Why not sparklyr?*
> sparklyr is an R package developed by RStudio Inc. to expose Spark API to R
> users. sparklyr includes MLlib API wrappers, but to the best of our knowledge
> they are not comprehensive. Also we propose a code-gen approach for this
> package to minimize work needed to expose future MLlib API, but sparklyr’s
> API is manually written.
> h1. Target Personas
> * Existing SparkR users who need more flexible SparkML API
> * R users (data scientists, statisticians) who wish to build Spark ML
> pipelines in R
> h1. Goals
> * R users can install SparkML from CRAN
> * R users will be able to import SparkML independent from SparkR
> * After setting up a Spark session R users can
> ** create a pipeline by chaining individual components and specifying their
> parameters
> ** tune a pipeline in parallel, taking advantage of Spark
> ** inspect a pipeline’s parameters and evaluation metrics
> ** repeatedly apply a pipeline
> * MLlib contributors can easily add R wrappers for new MLlib Estimators and
> Transformers
> h1. Non-Goals
> * Adding new algorithms to SparkML R package which do not exist in Scala
> * Parallelizing existing CRAN packages
> * Changing existing SparkR ML wrapping API
> h1. Proposed API Changes
> h2. Design goals
> When encountering trade-offs in API, we will chose based on the following
> list of priorities. The API choice that addresses a higher priority goal will
> be chosen.
> # *Comprehensive coverage of MLlib API:* Design choices that make R coverage
> of future ML algorithms difficult will be ruled out.
> * *Semantic clarity*: We attempt to minimize confusion with other packages.
> Between consciousness and clarity, we will choose clarity.
> * *Maintainability and testability:* API choices that require manual
> maintenance or make testing difficult should be avoided.
> * *Interoperability with rest of Spark components:* We will keep the R API
> as thin as possible and keep all functionality implementation in JVM/Scala.
> * *Being natural to R users:* Ultimate users of this package are R users and
> they should find it easy and natural to use.
> The API will follow familiar R function syntax, where the object is passed as
> the first argument of the method: do_something(obj, arg1, arg2). All
> functions are snake_case (e.g., {{spark_logistic_regression()}} and
> {{set_max_iter()}}). If a constructor gets arguments, they will be named
> arguments. For example:
> {code:java}
> > lr <- set_reg_param(set_max_iter(spark.logistic.regression()), 10),
> > 0.1){code}
> When calls need to be chained, like above example, syntax can nicely
> translate to a natural pipeline style with help from very popular[ magrittr
> package|https://cran.r-project.org/web/packages/magrittr/index.html]. For
> example:
> {code:java}
> > logistic_regression() %>% set_max_iter(10) %>% set_reg_param(0.01) ->
> > lr{code}
> h2. Namespace
> All new API will be under a new CRAN package, named SparkML. The package
> should be usable without needing SparkR in the namespace. The package will
> introduce a number of S4 classes that inherit from four basic classes. Here
> we will list the basic types with a few

---
Side note: The Java library we use for reading images does not support as many
image types as PIL, which we used in the image loader in
https://github.com/databricks/spark-deep-learning This should not block this
task, but it'd be worth poking around to see if there are alternative libraries
we could use from Java.

> The current API for the new image format is implemented as a standalone
> feature, in order to make it reside within the mllib package. As discussed in
> SPARK-21866, users should be able to load images through the more common
> spark source reader interface.
> This ticket is concerned with adding image reading support in the spark
> source API, through either of the following interfaces:
> - {{spark.read.format("image")...}}
> - {{spark.read.image}}
> The output is a dataframe that contains images (and the file names for
> example), following the semantics discussed already in SPARK-21866.
> A few technical notes:
> * since the functionality is implemented in {{mllib}}, calling this function
> may fail at runtime if users have not imported the {{spark-mllib}} dependency
> * How to deal with very flat directories? It is common to have millions of
> files in a single "directory" (like in S3), which seems to have caused some
> issues to some users. If this issue is too complex to handle in this ticket,
> it can be dealt with separately.

Bradley commented on SPARK-24359: --- It sounds like everyone is agreed on the fact that we need to be able to release SparkML more frequently than Spark (because of CRAN issues). The only remaining point of disagreement is whether we should keep SparkML in a separate repo for now. Here are some pros & cons I can think of. What do y'all think? Keeping SparkML in a separate repo: * Tagging releases would be easier. If a set of SparkML releases (2.4.0.1, 2.4.0.2) should be tested against a single Spark release (2.4.0), then separate repos could make this tracking easier. With a single repo, we would have to be careful to keep the 2.4.0.1 tag from containing changes not in 2.4.0, which would require some careful handling of release branches. * Testing could be simpler. When testing SparkML and Spark on the master branch, should SparkML test against Spark master or against the latest Spark release tag? Cons of keeping SparkML in a separate repo: * Changes in Spark could break SparkML. SparkML's CI / PR tests would test against Spark, but we should not have Spark PRs test against SparkML since that could create a loop blocking any change. * This might require more work to put build systems and CI tests in place. > SPIP: ML Pipelines in R > --- > > Key: SPARK-24359 > URL: https://issues.apache.org/jira/browse/SPARK-24359 > Project: Spark > Issue Type: Improvement > Components: SparkR >Affects Versions: 3.0.0 >Reporter: Hossein Falaki >Priority: Major > Labels: SPIP > Attachments: SparkML_ ML Pipelines in R-v2.pdf, SparkML_ ML Pipelines > in R-v3.pdf, SparkML_ ML Pipelines in R.pdf > > > h1.

[jira] [Created] (SPARK-24467) VectorAssemblerEstimator
Joseph K. Bradley created SPARK-24467: - Summary: VectorAssemblerEstimator Key: SPARK-24467 URL: https://issues.apache.org/jira/browse/SPARK-24467 Project: Spark Issue Type: New Feature Components: ML Affects Versions: 2.4.0 Reporter: Joseph K. Bradley In [SPARK-22346], I believe I made a wrong API decision: I recommended added `VectorSizeHint` instead of making `VectorAssembler` into an Estimator since I thought the latter option would break most workflows. However, I should have proposed: * Add a Param to VectorAssembler for specifying the sizes of Vectors in the inputCols. This Param can be optional. If not given, then VectorAssembler will behave as it does now. If given, then VectorAssembler can use that info instead of figuring out the Vector sizes via metadata or examining Rows in the data (though it could do consistency checks). * Add a VectorAssemblerEstimator which gets the Vector lengths from data and produces a VectorAssembler with the vector lengths Param specified. This will not break existing workflows. Migrating to VectorAssemblerEstimator will be easier than adding VectorSizeHint since it will not require users to manually input Vector lengths. Note: Even with this Estimator, VectorSizeHint might prove useful for other things in the future which require vector length metadata, so we could consider keeping it rather than deprecating it. -- This message was sent by Atlassian JIRA (v7.6.3#76005) - To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org

Joseph K. Bradley commented on SPARK-24359:
---
Clarification question: [~falaki] did you mean to say that the CRAN package
SparkML will be updated for every *minor* release (2.3, 2.4, etc.)? (I assume
you did not mean every major release (3.0, 4.0, etc.) since those only happen
every 2 years or so.)
I'd recommend we follow the same pattern as for the SparkR package: Updates to
SparkML and SparkR will require official Spark releases, limiting us to
patching SparkML only when there is a new Spark patch release (2.3.1, 2.3.2,
etc.). I feel like that's a lesser evil than the only other option I know of:
splitting off SparkR and/or SparkML into completely separate projects under
different Apache or non-Apache oversight. What do you think?

Bradley commented on SPARK-24359: --- Regarding separating repos: What's the conclusion? If feasible, I really hope this can be in the apache/spark repo to encourage contributors to add R wrappers whenever they add new MLlib APIs (just like it's pretty easy to add Python wrappers nowadays). Regarding CRAN releases: I'd expect it to be well worth it to say SparkML minor releases correspond to Spark minor releases. Users should not expect SparkML 2.4 to work with Spark 2.3 (since R would encounter missing Java APIs). I'm less sure about patch releases. (Ideally, this would all be solved by us following semantic versioning, but that would require that we never add Experimental APIs to SparkML.) If we can solve the maintainability issues with CRAN compatibility via integration tests, then I figure it'd be ideal to treat SparkML just like SparkR and PySpark, releasing in sync with the rest of Spark.

Description:
h1. Background and motivation
SparkR supports calling MLlib functionality with an [R-friendly
API|https://docs.google.com/document/d/10NZNSEurN2EdWM31uFYsgayIPfCFHiuIu3pCWrUmP_c/].
Since Spark 1.5 the (new) SparkML API which is based on [pipelines and
parameters|https://docs.google.com/document/d/1rVwXRjWKfIb-7PI6b86ipytwbUH7irSNLF1_6dLmh8o]
has matured significantly. It allows users build and maintain complicated
machine learning pipelines. A lot of this functionality is difficult to expose
using the simple formula-based API in SparkR.
We propose a new R package, _SparkML_, to be distributed along with SparkR as
part of Apache Spark. This new package will be built on top of SparkR’s APIs to
expose SparkML’s pipeline APIs and functionality.
*Why not SparkR?*
SparkR package contains ~300 functions. Many of these shadow functions in base
and other popular CRAN packages. We think adding more functions to SparkR will
degrade usability and make maintenance harder.
*Why not sparklyr?*
sparklyr is an R package developed by RStudio Inc. to expose Spark API to R
users. sparklyr includes MLlib API wrappers, but to the best of our knowledge
they are not comprehensive. Also we propose a code-gen approach for this
package to minimize work needed to expose future MLlib API, but sparklyr’s API
is manually written.
h1. Target Personas
* Existing SparkR users who need more flexible SparkML API
* R users (data scientists, statisticians) who wish to build Spark ML
pipelines in R
h1. Goals
* R users can install SparkML from CRAN
* R users will be able to import SparkML independent from SparkR
* After setting up a Spark session R users can
** create a pipeline by chaining individual components and specifying their
parameters
** tune a pipeline in parallel, taking advantage of Spark
** inspect a pipeline’s parameters and evaluation metrics
** repeatedly apply a pipeline
* MLlib contributors can easily add R wrappers for new MLlib Estimators and
Transformers
h1. Non-Goals
* Adding new algorithms to SparkML R package which do not exist in Scala
* Parallelizing existing CRAN packages
* Changing existing SparkR ML wrapping API
h1. Proposed API Changes
h2. Design goals
When encountering trade-offs in API, we will chose based on the following list
of priorities. The API choice that addresses a higher priority goal will be
chosen.
# *Comprehensive coverage of MLlib API:* Design choices that make R coverage
of future ML algorithms difficult will be ruled out.
* *Semantic clarity*: We attempt to minimize confusion with other packages.
Between consciousness and clarity, we will choose clarity.
* *Maintainability and testability:* API choices that require manual
maintenance or make testing difficult should be avoided.
* *Interoperability with rest of Spark components:* We will keep the R API as
thin as possible and keep all functionality implementation in JVM/Scala.
* *Being natural to R users:* Ultimate users of this package are R users and
they should find it easy and natural to use.
The API will follow familiar R function syntax, where the object is passed as
the first argument of the method: do_something(obj, arg1, arg2). All functions
are snake_case (e.g., {{spark_logistic_regression()}} and {{set_max_iter()}}).
If a constructor gets arguments, they will be named arguments. For example:
{code:java}
> lr <- set_reg_param(set_max_iter(spark.logistic.regression()), 10), 0.1){code}
When calls need to be chained, like above example, syntax can nicely translate
to a natural pipeline style with help from very popular[ magrittr
package|https://cran.r-project.org/web/packages/magrittr/index.html]. For
example:
{code:java}
> logistic_regression() %>% set_max_iter(10) %>% set_reg_param(0.01) -> lr{code}
h2. Namespace
All new API will be under a new CRAN package, named SparkML. The package should
be usable without needing SparkR in the namespace. The package will introduce a
number of S4 classes that inherit from four basic classes. Here we will list
the basic types with a few examples. An object of any child class can be
instantiated with a function call that starts with {{spark_}}.
h2. Pipeline & PipelineStage
A pipeline object contains one or more stages.
{code:java}
> pipeline <- spark_pipeline() %>% set_stages(stage1, stage2, stage3){code}
Where stage1, stage2, etc are S4 objects of a PipelineStage and pipeline is an
object of type Pipeline.
h2. Transformers
A Transformer is an algorithm that can transform one SparkDataFrame into
another SparkDataFrame.
*Example API:*
{code:java}
> tokenizer <- spark_tokenizer() %>%
set_input_col(“text”) %>%
set_output_col(“words”)
> tokenized.df <- tokenizer %>% transform(df) {code}

[jira] [Resolved] (SPARK-7132) Add fit with validation set to spark.ml GBT
[ https://issues.apache.org/jira/browse/SPARK-7132?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Joseph K. Bradley resolved SPARK-7132. -- Resolution: Fixed Fix Version/s: 2.4.0 Issue resolved by pull request 21129 [https://github.com/apache/spark/pull/21129] > Add fit with validation set to spark.ml GBT > --- > > Key: SPARK-7132 > URL: https://issues.apache.org/jira/browse/SPARK-7132 > Project: Spark > Issue Type: Improvement > Components: ML >Reporter: Joseph K. Bradley >Assignee: Weichen Xu >Priority: Minor > Fix For: 2.4.0 > > > In spark.mllib GradientBoostedTrees, we have a method runWithValidation which > takes a validation set. We should add that to the spark.ml API. > This will require a bit of thinking about how the Pipelines API should handle > a validation set (since Transformers and Estimators only take 1 input > DataFrame). The current plan is to include an extra column in the input > DataFrame which indicates whether the row is for training, validation, etc. > Goals > A [P0] Support efficient validation during training > B [P1] Support early stopping based on validation metrics > C [P0] Ensure validation data are preprocessed identically to training data > D [P1] Support complex Pipelines with multiple models using validation data > Proposal: column with indicator for train vs validation > Include an extra column in the input DataFrame which indicates whether the > row is for training or validation. Add a Param “validationFlagCol” used to > specify the extra column name. > A, B, C are easy. > D is doable. > Each estimator would need to have its validationFlagCol Param set to the same > column. > Complication: It would be ideal if we could prevent different estimators from > using different validation sets. (Joseph: There is not an obvious way IMO. > Maybe we can address this later by, e.g., having Pipelines take a > validationFlagCol Param and pass that to the sub-models in the Pipeline. > Let’s not worry about this for now.) -- This message was sent by Atlassian JIRA (v7.6.3#76005) - To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
