Assignee: Zoltán Borók-Nagy
> Log if memory-based admission is skipped
> ----------------------------------------
>
> Key: IMPALA-14451
> URL: https://issues.apache.org/jira/browse/IMPALA-14451
> Project: IMPALA
> Issue Type: Improvement
> Reporter: Zoltán Borók-Nagy
> Assignee: Zoltán Borók-Nagy
> Priority: Major
>
> When admission control is enabled, but max memory for pool is not configured,
> Impala skips memory-based admission completely, i.e. it doesn't even take
> available host memory into account.
> This behavior can lead to admitting many queries with large memory
> consumption, in which case the queries will fail with memory limit exceeded
> errors.
> From the current logs it is not clear what happens, I think we should add at
> least a LOG(INFO) message when memory-based admission is skipped.
