>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: applicationmaster
>    Affects Versions: 0.23.1

> 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.
