          Issue Type: Improvement
          Components: mapred
            Reporter: Amar Kamat


>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}
