--------------------------------------
Summary: Scalable Pool Configuration needs to consider executors
that are shutting down.
Key: IMPALA-8609
URL: https://issues.apache.org/jira/browse/IMPALA-8609
Project: IMPALA
Issue Type: Bug
Reporter: Andrew Sherman
Assignee: Andrew Sherman
IMPALA-8536 Adds Scalable Pool Configurations to Admission Controller. This
allows to Admission Controller to scale with the cluster size. In the initial
implementation of IMPALA-8536 the cluster size is obtained by counting
impala_server->GetKnownBackends().
This cluster size does not reflect the fact that some executors could be in
process of shutdown.
Admission Controller should ignore executors in process of shutdown.
If IMPALA-8460 (Simplify cluster membership management) is implemented, then
this functionality should probably be part of ClusterMembershipMgr.
