------------------------------------
Summary: Allow setting separate mem_limit for coordinators (was: Allow
setting separate mem_limit for coordinators and executors)
> Allow setting separate mem_limit for coordinators
> -------------------------------------------------

> Key: IMPALA-10860
> URL: https://issues.apache.org/jira/browse/IMPALA-10860
> Project: IMPALA
> Issue Type: Task
> Reporter: Abhishek Rawat
> Assignee: Abhishek Rawat
> Priority: Major
>
> The mem_limit query option applies to all impala coordinators and executors.
> This may not be ideal for dedicated coordinators, since they generally need
> less memory per query and having same memory limit will reduce system wide
> query concurrency.
> We could add new query options:
>
> {code:java}
> mem_limit_coordinators
> mem_limit_executors
> {code}
>
