-------------------------------------
Resolution: Duplicate
Duplicate of MAPREDUCE-343.
> Show why the job failed (e.g. Job ___ failed because task ____ failed 4
> times)
> -------------------------------------------------------------------------------
>
> Key: MAPREDUCE-2075
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2075
> Project: Hadoop Map/Reduce
> Issue Type: New Feature
> Reporter: Koji Noguchi
> Priority: Minor
> Fix For: 0.22.0
>
>
> When our users have questions about their jobs' failure, they tend to
> copy&paste all the userlog exceptions they see on the webui/console.
> However, most of them are not the one that caused the job to fail. When we
> tell them 'This task failed 4 times", sometimes that's enough information for
> them to solve the problem on their own.
> It would be nice if jobclient or job status page shows the reason for the job
> being flagged as fail.
