Resolution: Fixed
> Take codegen cache memory into account for admission controller
> ---------------------------------------------------------------
>
> Key: IMPALA-11786
> URL: https://issues.apache.org/jira/browse/IMPALA-11786
> Project: IMPALA
> Issue Type: Improvement
> Reporter: Yida Wu
> Assignee: Yida Wu
> Priority: Major
>
> Currently admission controller is not aware of the memory usage of the
> codegen cache, and the codegen cache is long-running and damon-level, this
> may lead to more allocation failures during heavy workload scenario when the
> available memory is running out. One solution is to subtract the codegen
> cache capacity from the available memory that admission controller can use
> when initialization, so that the admission controller would take account of
> the usage of codegen cache since the beginning.
