Use an internal representation of query states in ClientRequestState

    XMLWordPrintableJSON

Details

    Description

      Having an internal representation of states will be useful as we can conveniently add/remove new states and develop logic around those eg. [initialization, analysis complete, planning complete/queued, running] (set the stage for IMPALA-2568 and its sub-tasks), [cancelled, exception etc] (IMPALA-1262).
      We can easily convert it to client (HS2 and Beeswax) specific states and ensure there are no client visible changes.
