Description

Admission Control's queue timeout is controlled by impalad startup parameter. That means all queries get the same timeout amount.

In practice, it would be a lot easier if the user can control the timeout setting on a per-query basis. For example, long running query with slow SLA can have a very very high timeout while interactive query might choose to have a very short timeout.
