Change subject: IMPALA-14451: Log if memory-based admission is skipped ...................................................................... IMPALA-14451: Log if memory-based admission is skipped 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, potentially causing query failures due to memory exhaustion. Fixing the above behavior might cause regressions in some workloads, so this patch just adds a new log message which makes it clear why a query gets admitted, and also mentions possible failures.
