Summary: PROCESSING_COST_MIN_THREADS fail to cap minimum
parallelism
Key: IMPALA-12032
URL: https://issues.apache.org/jira/browse/IMPALA-12032
Project: IMPALA
Issue Type: Bug
Reporter: Riza Suminto
Assignee: Riza Suminto
PROCESSING_COST_MIN_THREADS suppose to be a lower bound of per node parallelism
when CPU costing algorithm adjust fragment parallelism across executor group
set. But PlanFragment.adjustToMaxParallelism() does not take account of it
during adjustment.
