Abhishek Rawat updated IMPALA-10860:
------------------------------------
Description:
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
{code}
