> Key: IMPALA-7357
> URL: https://issues.apache.org/jira/browse/IMPALA-7357
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Reporter: Tim Armstrong
> Priority: Major
> Labels: admission-control
>
> We could consider reducing the update frequency further (maybe just for
> coordinators??) and possibly adding some jitter to the admission process to
> prevent overadmission when multiple queries are submitted at the same time to
> different coordinators.
> The problem is that the coordinators independently make admission decisions
> before the change in state from previous decisions is propagated to other
> coordinators.
