[jira] [Commented] (SPARK-22622) OutOfMemory thrown by Closure
Serializer
[ https://issues.apache.org/jira/browse/SPARK-22622?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16269894#comment-16269894 ]
Raghavendra commented on SPARK-22622:
-------------------------------------
The output of previous Stage is around 70GB and my driver memory is 225GB. Why am i getting an OOM when there is sufficient memory.
Also, since this is closure serializer, isnt it only serializing the Physical Plan and not the RDD?

> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.2.0
> Environment: Spark 2.2.0
> Hadoop 2.9.0
> Reporter: Raghavendra
> Priority: Critical
>
> While moving from a Stage to another, the Closure serializer is trying to Serialize the Closures and throwing OOMs.
> This is happening when the RDD size crosses 70 GB.
> I set the Driver Memory to 225 GB and yet the error persists.
