Subject [jira] [Commented] (MAPREDUCE-3928) App GUI Cluster->Applications UI has confusing job status report
Date Wed, 11 Apr 2012 22:49:20 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3928?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13252008#comment-13252008

Anupam Seth commented on MAPREDUCE-3928:
----------------------------------------

Agree that it is an issue of user education for now and hence closing the JIRA. 

In the future, though, we could potentially look at some interesting possibilities to reduce
the learning curve for users transitioning from the 1.0 / 0.20 world such as having an MR
specific GUI or maybe easier fixes such as column based filtering on the RM, but that is lower
priority and can be dealt with as the community deems the best approach with an enhancement
request at that time.

>             Project: Hadoop Map/Reduce

> 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.
