[jira] [Created] (HIVE-20648) LLAP: Vector group by operator should use memory per executor

Prasanth Jayachandran created HIVE-20648:
--------------------------------------------

             Summary: LLAP: Vector group by operator should use memory per executor
                 Key: HIVE-20648
                 URL: https://issues.apache.org/jira/browse/HIVE-20648
             Project: Hive
          Issue Type: Bug
    Affects Versions: 4.0.0, 3.2.0
            Reporter: Prasanth Jayachandran
            Assignee: Prasanth Jayachandran


HIVE-15503 treatment has to be applied for vector group by operator as well. Vector group by currently uses MemoryMX bean to get heap usage and heap max memory which will not work for LLAP. Instead it should use memory per executor as upper bound to make flush decision.
