Raghavendra created SPARK-22622:
-----------------------------------
Summary: OutOfMemory thrown by Closure Serializer
Key: SPARK-22622
URL: https://issues.apache.org/jira/browse/SPARK-22622
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: Blocker
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.
Exception in thread "dag-scheduler-event-loop" java.lang.OutOfMemoryError:
Requested array size exceeds VM limit
