Manish Maheshwari commented on IMPALA-12264:
--------------------------------------------
e.g. Add a control in IAC to limit -
* the number of concurrent sessions open at given time
* the number of concurrent queries open at given time
* Futher there should be both a control both at a pool level and also a an
Impala service level to say - john can run max 5 concurrent queries per pool
and max 15 queries for the entire impala service.
