URL: https://issues.apache.org/jira/browse/SPARK-24437
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.2.0
Reporter: gagan taneja
There seems to memory leak withÂ
org.apache.spark.sql.execution.joins.UnsafeHashedRelation
We have a long running instance of STS.
With each query execution requiring Broadcast Join, UnsafeHashedRelation is
getting added for cleanup in ContextCleaner. This reference of
UnsafeHashedRelation is being held at some other Collection and not becoming
eligible for GC and because of this ContextCleaner is not able to clean it.
