      Description

      The 0.23.1 Application GUI has some potential usability issues and confusion
      points with respect to job status, from a user's perspective.

      Currently, when starting from the App UI base link of
      http://<RM_HOST>:8088/cluster, the main window shows "All Applications", and in
      the upper left corner is the "Cluster" pulldown, opened up showing the
      following list:

      About
      Nodes
      Applications

      • New
      • Submitted
      • Accepted
      • Running
      • Finished
      • Failed
      • Killed
        Scheduler

      When jobs are submitted, they show up in the pre-final states, like Accepted
      and Running. however after completion, no matter on the final outcome of a job
      (SUCCESS, KILLED or FAILED), all jobs are listed under FINISHED, this is okay
      since any completion result qualifies as Finished, but the FAILED and KILLED
      jobs do not appear in the corresponding links for FAILED or KILLED.

      Clicking on FAILED or KILLED reports "No data available in table", even with
      Failed or Killed jobs showing up in the FINISHED link. This can be very
      confusing to a user checking on their jobs, especially for someone using the
      direct URL links, such as:

      http://<RM_HOST>:8088/cluster/apps/FAILED
      http://<RM_HOST>:8088/cluster/apps/KILLED

      Another potential issue is that the RM and AM each have their own
      interpretation of a job's result, so the State and FinalStatus reported in the
      Cluster Metrics display may not align with the defined states in the Cluster
      pulldown. It would be useful to clearly delineate areas of the GUI wrt the
      component visible states of a user's job.
