-------------------------------------
Summary: Incomplete ResourceProfile at multi-class AggregationNode
Key: IMPALA-13400
URL: https://issues.apache.org/jira/browse/IMPALA-13400
Project: IMPALA
Issue Type: Bug
Components: Frontend
Affects Versions: Impala 4.4.0
Reporter: Riza Suminto
Assignee: Riza Suminto
AggregationNode.computeAggClassResourceProfile() call setSpillableBufferBytes
and setMaxRowBufferBytes. However, ResourceProfile for each aggregation class
are merged using ResourceProfile.sum() which waive setting both fields.

It should use ResourceProfile.combine() that will pick max
SpillableBufferBytes and max MaxRowBufferBytes.
