                 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.
