I agree that the use cases are limited to single trees. You kind of lose interpretability if you train the tree to maximum depth. It helps in improving interpretability while also improving on generalization performance. 3. It is intuitive to prune the tree during training (i.e stop training after the validation error increases) . However this is very similar to just having a stopping criterion such as maximum depth, minimum samples in each node (except that the stopping criteria is dependent on validation data) And is quite uncommon to do it. The standard practise (at least according to my lectures) is to train the tree to full depth and remove the leaves according to validation data. However, if you feel that #14351 is more important, I can focus on that. was (Author: mechcoder): 1. I agree that the use cases are limited to single trees.

Kafka is a lynchpin of many production scenarios and skipping 0.9 was bad enough for Spark.

Bradley commented on SPARK-3155: -- A few thoughts: (1) I'm less sure about the priority of this task now. I've had a hard time identifying use cases. Few people train single trees. For forests, people generally want to overfit each tree a bit, not prune. For boosting, people generally use shallow trees so that there is no need for pruning. It would be useful to identify real use cases before we implement this feature. (2) I agree the 2 args are validation data + error tolerance. (3) Will most users want to prune during or after training? * During training: More efficient * After training: Allows multiple prunings using different error tolerances I'd say that [SPARK-14351] is the highest priority single-tree improvement I know of right now. > Support DecisionTree pruning > > > Key: SPARK-3155 > URL: https://issues.apache.org/jira/browse/SPARK-3155 > Project: Spark > Issue Type: Improvement > Components: MLlib >Reporter: Joseph K.

Hyukjin Kwon commented on SPARK-15918:
--
Actually, I met this case before and was thinking it might be an issue.
However, I realised it seems actually not after executing the equelvant quries
in other several DBMS and checking some documentations such as
https://msdn.microsoft.com/en-us/library/ms180026.aspx and
http://www.w3schools.com/sql/sql_union.asp that say
{quote}
the columns in each SELECT statement must be in the same order
{quote}
I haven't read about the official SQL standard though, I am also pretty sure
that this is not an issue.

[jira] [Commented] (SPARK-12177) Update KafkaDStreams to new Kafka 0.10 Consumer API
[ https://issues.apache.org/jira/browse/SPARK-12177?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=15328699#comment-15328699 ] Mark Grover commented on SPARK-12177: - Hi Ismael and Cody, My personal opinion was to hold off because a) The new consumer API was still marked as beta, and so I wasn't sure of the compatibility guarantees, which Kafka did seem to break a little (as discussed [here|http://mail-archives.apache.org/mod_mbox/kafka-dev/201605.mbox/%3CCAKm=r7v5jgg9qxgjioczdph9vej57m46ngy_626kiq-ovdx...@mail.gmail.com%3E]) b) the real benefit is security - I am personally a little more biased towards authentication (Kerberos) than encryption, so I was just waiting for delegation tokens to land. Now, that 0.10.0 is released, there's a good chance delegation tokens would land in Kafka 0.11.0, and the new consumer API is marked stable, I am more open to this PR being merged, it's been around for too long anyways. Cody, what do you say? Any reason you'd want to wait? If not, we can make a case for this going in now. As far the logistics of whether this belongs in Apache Bahir or not - today, I don't have a strong opinion on where kafka integration should reside. What I do feel strongly about, like Cody said, is that the old consumer API integration and new consumer API integration should reside in the same place. Since the old integration is in Spark, that's where the new makes sense. If a vote on Apache Spark results in Kafka integration to be taken out, both the new and the old in Apache Bahir would make sense. > Update KafkaDStreams to new Kafka 0.10 Consumer API > --- > > Key: SPARK-12177 > URL: https://issues.apache.org/jira/browse/SPARK-12177 > Project: Spark > Issue Type: Improvement > Components: Streaming >Affects Versions: 1.6.0 >Reporter: Nikita Tarasenko > Labels: consumer, kafka > > Kafka 0.9 already released and it introduce new consumer API that not > compatible with old one.

The last time I encounter FileOutputStream.writeBytes hangs is because I
created a Process in Java but didn't consume its input stream and error stream.
Finally, the underlying buffer was full and blocked the Process.

By the way, how did you use Spark? Did you just run it or call it via some
Process APIs?

Oh, the thread state is `RUNNABLE`. So not a deadlock. Could you check you
disk? Maybe some bad disks cause the hang.

[~tejasp] Probably some deadlock in Spark. It would be great if you can provide
the full jstack output.

-
[~zsxwing] : This does not repro consistently but happens one off cases.. that
too over different jobs. I have seen this 3-4 times in last week. The type of
jobs I was running were pure SQL queries with SELECT, JOINs and GROUP BY. Sorry
I cannot share the exact query neither the data. But I am quite positive that
this problem would have nothing to do with the query being ran.

Description:
We removed some deprecated method in SQLContext in branch Spark 2.0.
For example:
{code}
@deprecated("Use read.json(). This will be removed in Spark 2.0.", "1.4.0")
def jsonFile(path: String): DataFrame = {
read.json(path)
}
{code}
These deprecated method may be used by existing third party data source. We
probably want to add them back to remain source code level backward
compatibility.

The reason is that maxRunningTasks seems brittle to the underlying setup -- if someone configures a certain maximum number of tasks, and then a few machines die, the maximum may no longer be reasonable (e.g., it may become larger than the number of machines in the cluster). The other benefit is symmetry with minShare, as Mark mentioned. [~njw45] why did you chose maxRunningTasks, as opposed to maxShare? Are there other reasons that maxRunningTasks makes more sense? > Job Scheduling Within Application Suffers from Priority Inversion > - > > Key: SPARK-15176 > URL: https://issues.apache.org/jira/browse/SPARK-15176 > Project: Spark > Issue Type: Bug > Components: Scheduler >Affects Versions: 1.6.1 >Reporter: Nick White > > Say I have two pools, and N cores in my cluster: > * I submit a job to one, which has M >> N tasks > * N of the M tasks are scheduled > * I submit a job to the second pool - but none of its tasks get scheduled > until a task from the other pool finishes! > This can lead to unbounded denial-of-service for the second pool - regardless > of `minShare` or `weight` settings.

[jira] [Commented] (SPARK-15918) unionAll returns wrong result when two dataframes has schema in different order

Hi, [~Prabhu Joseph].
Instead of changing one of the tables, you just need to use explicit `select`.
If `df1(a,b)` and `df2(b,a)`, please do the followings.
{code}
df1.union(df2.select("a", "b"))
{code}
IMHO, this is not a problem.

[jira] [Created] (SPARK-15930) Add Row count property to FPGrowth model
John Aherne created SPARK-15930: --- Summary: Add Row count property to FPGrowth model Key: SPARK-15930 URL: https://issues.apache.org/jira/browse/SPARK-15930 Project: Spark Issue Type: Improvement Components: MLlib Affects Versions: 1.6.1 Reporter: John Aherne Priority: Minor Add a row count property to MLlib's FPGrowth model. When using the model from FPGrowth, a count of the total number of records is often necessary. It appears that the function already calculates that value when training the model, so it would save time not having to do it again outside the model. Sorry if this is the wrong place for this kind of stuff. I am new to Jira, Spark, and making suggestions. -- This message was sent by Atlassian JIRA (v6.3.4#6332) - To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org

[~gbow...@fastmail.co.uk]
{{mapPartitions}} expects a function that takes an iterator as input then
outputs an iterable sequence, and your function in the example is actually
providing this. I think what is going on here is your function will map the
iterator to a numpy array, that internally will be something like
{noformat}array([[0, 1, 2, 3, 4], [5, 6, 7, 8, 9]]){noformat} for the first
partition, then {{collect}} will iterate over that sequence and return each
element, which will also be a numpy array, so you get {noformat}array([0, 1, 2,
3, 4]), array([5, 6, 7, 8, 9])) {noformat} for the first 2 elements and so on..
I believe this is working as it is supposed to, and in general,
{{mapPartitions}} will not usually give the same result as {{map}} - it will
fail if the function does not return a valid sequence. The documentation could
perhaps be a little clearer in that regard.

> # p <- p + scale_fill_manual(values = set2[groups])
> # # p <- p + scale_fill_brewer(palette = "Set2") +
> scale_color_brewer(palette = "Set2")
> # p <- p + scale_x_date(labels = date_format("%m/%d\n%a"))
> # p
> {code}
> I get the following error message
> {quote}
> :16:1: unexpected input
> 15: # p <- p + scale_x_date(labels = date_format("%m/%d
> 16: %a"))
> ^
> {quote}
> After I remove the backslash in "date_format("%m/%d\n%a"))", it works fine.

[jira] [Commented] (SPARK-15923) Spark Application rest api returns "no such app: "

Thomas Graves commented on SPARK-15923:
---
can you give some more details?
Did you have your application history log dir configured
(spark.history.fs.logDirectory)? Was the event log for your Spark Pi written
to that directory?
Was the history server being slow in loading the file (see the log file for the
history server)?
does the UI show it going to http://:18080?
