[jira] [Created] (IMPALA-9976) Implement fault tolerance for the admission control service

Thomas Tauber-Marshall created IMPALA-9976:
----------------------------------------------

             Summary: Implement fault tolerance for the admission control service
                 Key: IMPALA-9976
                 URL: https://issues.apache.org/jira/browse/IMPALA-9976
             Project: IMPALA
          Issue Type: Sub-task
          Components: Distributed Exec
            Reporter: Thomas Tauber-Marshall


If the new admission control daemon fails, it would be good to be able to recover gracefully.

Most of the admission control state is already stored in the statestore, so it should be possible to launch a new admission control daemon and have it catch up by retrieving everything from the statestore. Already running queries should not be affected.
