-----------------------------------

             Summary: idle_query_timeout setting in Impala needs more clarification
                 Key: IMPALA-7162
                 URL: https://issues.apache.org/jira/browse/IMPALA-7162
             Project: IMPALA
          Issue Type: Documentation
          Components: Docs
    Affects Versions: Impala 2.6.0
            Reporter: Laurel Hale


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.
