                 Key: HADOOP-5768
                 URL: https://issues.apache.org/jira/browse/HADOOP-5768
             Project: Hadoop Core
          Issue Type: New Feature
          Components: mapred
    Affects Versions: 0.20.0
            Reporter: Owen O'Malley
            Assignee: Owen O'Malley
             Fix For: 0.21.0


It would be very nice when tracking down tasks that have strange values for their counters, if there was a command line tool to print out the task attempts and their counters and diagnostic messages. I propose adding switches to -list-attempt-ids to accomplish that:

{quote}
hadoop job -list-attempt-ids [-counters] [-diagnostics] <job> <type> <state>
{quote}
