Subject [jira] Created: (HADOOP-5541) Place holder for job level diagnostic information

Place holder for job level diagnostic information

                 Key: HADOOP-5541
                 URL: https://issues.apache.org/jira/browse/HADOOP-5541
             Project: Hadoop Core
          Issue Type: Bug
          Components: mapred
            Reporter: Vinod K V

In some scenarios, when framework itself fails/kills the job, there is no clear way for the
user to know what happened to the job. A job level diagnostic string, perhaps displayed in
JobStatus when queried from command line or view from the web ui would help. Two cases I can
think of:
 - When a job is failed when it transgresses mapred.jobtracker.maxtasks.per.job.
 - When CapacityScheduler kills a job when it detects that the job's memory requirements can
never be meant.
