Subject [jira] [Commented] (SPARK-27927) driver pod hangs with pyspark 2.4.3 and master on kubenetes
Date Mon, 15 Jul 2019 13:11:00 GMT

    [ https://issues.apache.org/jira/browse/SPARK-27927?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16885217#comment-16885217

Edwin Biemond commented on SPARK-27927:
---------------------------------------

Thanks you so much for your time and  indeed all is fine on spark 2.4.3 when I revert SPARK-26742
commit -> k8s back to kubernetes-client-3.0.0.jar & kubernetes-model-2.0.0.jar

I understand we need to do patching but spark 2.4.3 is maintenance release and this should
never happen. 

especially If we not even patch jackson-core to 2.9.9 because of security risks 

 

This has to be done in 3.0.0 and have a proper fix for this blocking threads plus all the
time to resolve this.

>          Issue Type: Bug
>          Components: Kubernetes, PySpark
>    Affects Versions: 3.0.0, 2.4.3
>         Environment: k8s 1.11.9
> spark 2.4.3 and master branch.

> When we run a simple pyspark on spark 2.4.3 or 3.0.0 the driver pods hangs and never
calls the shutdown hook. 
> {code:java}
> #!/usr/bin/env python
> from __future__ import print_function
> import os
> import os.path
> import sys
> # Are we really in Spark?
> from pyspark.sql import SparkSession
> spark = SparkSession.builder.appName('hello_world').getOrCreate()
> print('Our Spark version is {}'.format(spark.version))
> print('Spark context information: {} parallelism={} python version={}'.format(
> str(spark.sparkContext),
> spark.sparkContext.defaultParallelism,
> spark.sparkContext.pythonVer
> ))
> {code}
> When we run this on kubernetes the driver and executer are just hanging. We see the output
of this python script. 
> {noformat}
> bash-4.2# cat stdout.log
> Our Spark version is 2.4.3
> Spark context information: <SparkContext master=k8s://https://kubernetes.default.svc:443
appName=hello_world> parallelism=2 python version=3.6{noformat}
> What works
>  * a simple python with a print works fine on 2.4.3 and 3.0.0
>  * same setup on 2.4.0
>  * 2.4.3 spark-submit with the above pyspark
