--------------------------------------------
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.
