Tim Armstrong updated IMPALA-3922:

Summary: Support yarn.scheduler.fair.allow-undeclared-pools option in
fair-scheduler.xml (was: Admission control pools are dynamically created even
when dynamic queues are disabled in YARN)
> Support yarn.scheduler.fair.allow-undeclared-pools option in
> fair-scheduler.xml

>
> Key: IMPALA-3922
> URL: https://issues.apache.org/jira/browse/IMPALA-3922
> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Affects Versions: Impala 2.3.0
> Reporter: Jim Halfpenny
> Priority: Minor
> Labels: admission-control, resource-management
>
> When the YARN parameter yarn.scheduler.fair.allow-undeclared-pools is set to
> false Impala still creates resource pools dynamically. This leads to
> unexpected behaviour when configuring admission controls.
> Impala uses the resource pool root.<username> if no pool is specified.
> Queries that do not
> specify a pool will trigger creation of a new one, which is likely not what
> the user intended. This behaviour occurs even when
> yarn.scheduler.fair.user-as-default-queue is set to false.
