[jira] [Created] (PIG-3797) Fix some memory leaks affecting container reuse

Rohini Palaniswamy created PIG-3797:
---------------------------------------

             Summary: Fix some memory leaks affecting container reuse
                 Key: PIG-3797
                 URL: https://issues.apache.org/jira/browse/PIG-3797
             Project: Pig
          Issue Type: Sub-task
            Reporter: Rohini Palaniswamy
            Assignee: Rohini Palaniswamy
             Fix For: tez-branch


PigCombiner.sJobContext and PhysicalOperator.reporter hold references to the WrappedReducer$Context which in turn holds TezOutputContextImpl which holds references to the buffers in DefaultSorter. This was causing OOM after the container was reused 2 or 3 times. Debugged this with L17.pig in pigmix.
