-----------------------------------
Summary: Support using non-default executor groups for planner
Key: IMPALA-12312
URL: https://issues.apache.org/jira/browse/IMPALA-12312
Project: IMPALA
Issue Type: Improvement
Reporter: YifanZhang
An Impala cluster can contain multiple executor group sets, including a default
executor group and non-default executor groups. The current planner always
tends to pick the default executor group for scheduling a query because only
the default executor group is included in the update message that is sent to
the frontend.
When we set a non-default request_pool for a query, the generated plan is still
based on the default executor group, which leads to an inaccurate execution
plan.
This can be improved by sending all configured executor groups' information to
the frontend.
