----------------------------------
Summary: Clean up hacky use of MemoryManager inside of
HashedRelation
Key: SPARK-11309
URL: https://issues.apache.org/jira/browse/SPARK-11309
Project: Spark
Issue Type: Sub-task
Components: SQL
Reporter: Josh Rosen
In HashedRelation, there's a hacky creation of a new MemoryManager in order to
handle broadcasting of BytesToBytesMap:
https://github.com/apache/spark/blob/85e654c5ec87e666a8845bfd77185c1ea57b268a/sql/core/src/main/scala/org/apache/spark/sql/execution/joins/HashedRelation.scala#L323
Something similar to this has existed for a while, but the code recently became
much messier as an indirect consequence of my memory manager consolidation
patch. We should see about cleaning this up and removing the hack.
