Key: HADOOP-3906
URL: https://issues.apache.org/jira/browse/HADOOP-3906

>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.
