[jira] [Commented] (MAPREDUCE-343) Failed jobs should report the
reason of failure on the web ui
[ https://issues.apache.org/jira/browse/MAPREDUCE-343?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13054860#comment-13054860 ]
Harsh J commented on MAPREDUCE-343:
-----------------------------------
What should the statistics be like?
Something simple like {{Reason: N Tasks Failed}} or fairly more complex including exception names and such?

> From user's perspective it is difficult to detect why the job failed . Users might need to go through the jobtracker logs or task attempts list to see why the job failed. It would be good to show the reason on the job web ui. Something like
> {code}
> User: bob
> Job Name: example
> Job File: hdfs://location/job.xml
> Status: Failed
> Reason : Map/Reduce task # 47 failed x number of times.
> {code}
