[jira] [Created] (IMPALA-7256) Aggregator mem usage isn't reflected in summary

Thomas Tauber-Marshall created IMPALA-7256:
----------------------------------------------

             Summary: Aggregator mem usage isn't reflected in summary
                 Key: IMPALA-7256
                 URL: https://issues.apache.org/jira/browse/IMPALA-7256
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
    Affects Versions: Impala 3.1.0
            Reporter: Thomas Tauber-Marshall
            Assignee: Thomas Tauber-Marshall


Since IMPALA-110 (part 2) went in, which refactored 'PartitionedAggregationNode' and introduces 'Aggregator', the memory used by Aggregator is not reflected in the exec summary, where it should be listed under the corresponding AggregationNode/StreamingAggregationNode, as Aggregator's MemTracker is initialized with the RuntimeState::instance_mem_tracker as its parent, rather than ExecNode::mem_tracker
