----------------------------------
Labels: (was: newbie)
> Increase default threadpool size for statestore heartbeat and topic update
> --------------------------------------------------------------------------
>
> Key: IMPALA-4140
> URL: https://issues.apache.org/jira/browse/IMPALA-4140
> Project: IMPALA
> Issue Type: Improvement
> Components: Distributed Exec
> Affects Versions: Impala 2.2
> Reporter: Juan Yu
> Priority: Major
>
> Default threadpool size for statestore heartbeat and topic update is 10. For
> a large cluster this could be too small and cause membership request and
> topic update tasks not being processed in timely manner.
> We should increase default size to probably 2~3 times of # cores.
