----------------------------------

             Summary: RuntimeFilter memory leak due to BF ByteBuf ownership transferring 
                 Key: DRILL-6947
                 URL: https://issues.apache.org/jira/browse/DRILL-6947
             Project: Apache Drill
          Issue Type: Improvement
            Reporter: weijie.tong
            Assignee: weijie.tong
             Fix For: 1.16.0


RuntimeFilter's BF ByteBuf ownership should be transferred right at broadcast and random hash cases. Currently due to we not treat this transferring reasonable, it caused the memory leak.

To broadcast case,the HashJoin operator's allocator allocated the BF, the allocated BF's ownership should be transferred to its receiver : the FragmentContextImpl or the final RuntimeFilter operator. Otherwise, the OperatorContextImpl's close method will complain about the memory leak when closing the corresponding allocator.
