Subject [jira] Commented: (MAPREDUCE-2075) Show why the job failed (e.g. Job ___ failed because task ____ failed 4 times)

Seems like a duplicate of MAPREDUCE-343.

> 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.
