Summary: 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
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.
