Subject [jira] [Commented] (MAPREDUCE-3928) App GUI Cluster->Applications UI has confusing job status report
Date Mon, 27 Feb 2012 22:27:50 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3928?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13217638#comment-13217638

Vinod Kumar Vavilapalli commented on MAPREDUCE-3928:
----------------------------------------------------

bq. 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.
This is the main point. Let me clarify:
 - The final state of the application is fundamentally different from the FinalStatus of the
application.
 - FinalStatus of an application is a separate API for custom frameworks to expose their final
status.
 - On the RM UI, the state always represents the state of the application.
 - In MapReduce case, a Failed/Killed job still corresponds to a FINISHED application.

Given that, is it that you are expecting Failed/Killed mapreduce jobs to appear under FAILED/KILLED
applications list?

>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: applicationmaster
>    Affects Versions: 0.23.1
>            Reporter: patrick white
>
> 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.
