[jira] [Created] (IMPALA-5852) Improve MINIMUM_RESERVATION_UNAVAILABLE message

Tim Armstrong created IMPALA-5852:
-------------------------------------

             Summary: Improve MINIMUM_RESERVATION_UNAVAILABLE message
                 Key: IMPALA-5852
                 URL: https://issues.apache.org/jira/browse/IMPALA-5852
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
    Affects Versions: Impala 2.10.0
            Reporter: Tim Armstrong
            Assignee: Tim Armstrong


Now that queries with too-low mem_limits are rejected in admission control, we can refine this error message.

Assuming that admission control is enabled (which is the default and only recommended configuration), the only reason that query startup should fail is if memory is oversubscribed on the Impala daemon.
