> This Jira is created on behalf of Sudarshan Sharma:
> 1) Please refer to the following Impala documentation:
> [http://impala.apache.org/docs/build3x/html/topics/impala_timeouts.html]
> 2) Please see the section where idle_query_timeout is explained.
> *************************
> Request:-
> *************************
> We've mentioned that idle_query_timeout cancels the query.
> Can we please elaborate it further and mention that query still stays open (after being cancelled) and consumes a slot in Impala admission control? Therefore, though idle_query_timeout helps in saving some resources at Impala end, you may still want to configure idle_Session_timeout to same value since idle_Session_timeout even closes the query for idle sessions (instead of just cancelling) though the requirement for it to trigger is session should stay idle.
