I see that the spark version being used in the project that you mentioned
is 1.6.0. I would suggest that you take a look at some blogs related to
Spark 2.0 Pipelines, Models in new ml package. The new ml package's API as
of latest Spark 2.1.0 release has no way to call predict on single

been unimpressed with the performance numbers - as well as your choice to
reimplement own non-standard "pmml-like" mechanism which incurs
I am using pyspark 2.1 and am wondering how to convert a flat file, with

Hi,
I was trying Spark version 1.6.0 when I ran into the error mentioned in the
following Hive JIRA.
https://issues.apache.org/jira/browse/HIVE-5825
This error was there in both cases : either using SQLContext or HiveContext.
Any indication if this has been fixed in a higher spark version ? If
I am getting this error with Spark 2. which works with CDH 5.5.1 (Spark
1.5).
Admittedly I am messing around with Spark-shell. However, I am surprised
why this does not work with Spark 2 and is ok with CDH 5.1

Except of course lda als and neural net modelfor them the model need to
be either prescored and cached on a kv store or the matrices / graph should
be kept on kv store to access them using a REST API to serve the
output..for neural net its more fun since its a distributed or local graph

If we expose an API to access the raw models out of PipelineModel can't we
call predict directly on it from an API ? Is there a task open to expose
the model out of PipelineModel so that predict can be called on itthere
is no dependency of spark context in ml model...

- In Spark 2.0 there is a class called PipelineModel. I know that the
title says pipeline but it is actually talking about PipelineModel trained
via using a Pipeline.
- Why PipelineModel instead of pipeline? Because usually there is a
series of stuff that needs to be done when doing
I am not sure why I will use pipeline to do scoring...idea is to build a
model, use model ser/deser feature to put it in the row or column store of
choice and provide a api access to the model...we support these primitives
in github.com/Verizon/trapezium...the api has access to spark context in
this is a general problem with checkpoint, one of the least understood
operations i think.
checkpoint is lazy (meaning it doesnt start until there is an action) and
asynchronous (meaning when it does start it is its own computation). so
basically with a checkpoint the rdd always gets computed
Does this support Java 7?
What is your timezone in case someone wanted to talk?

Hi Direceu
Thanks your right! that did work
But now im facing an even bigger problem since i dont have access to change
the underlying data, I just want to apply a schema over something that was
written via the sparkContext.newAPIHadoopRDD
Basically I am reading in a RDD[JsonObject] and would

Hi All
I would like to specify a schema when reading from a json but when trying
to map a number to a Double it fails, I tried FloatType and IntType with no
joy!
When inferring the schema customer id is set to String, and I would like to
cast it as Double
so df1 is corrupted while df2 shows
Hi,
I'd say the error says it all :
Caused by: NoNodeAvailableException[None of the configured nodes are
available: [{#transport#-1}{XX.XXX.XXX.XX}{XX.XXX.XXX.XX:9300}]]

Hi,
I have a table in Hive(data is stored as avro files).
Using python spark shell I am trying to join two datasets
events = spark.sql('select * from mydb.events')
intersect = events.where('attr2 in (5,6,7) and attr1 in (1,2,3)')
intersect.count()
But I am constantly receiving the following

zero() on scala.runtime.VolatileObjectRef has been introduced in Scala 2.11
You probably have a library compiled against Scala 2.11 and running on a
Scala 2.10 runtime.
See

Ingesting from Hive tables back into Oracle. What mechanisms are in place
to ensure that data ends up consistently into Oracle table and Spark is
notified when Oracle has issues with data ingested (say rollback)?
