Robert Kanter created MAPREDUCE-6627:
----------------------------------------

             Summary: Add machine-readable output to mapred job -history command
                 Key: MAPREDUCE-6627
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6627
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: client
    Affects Versions: 2.9.0
            Reporter: Robert Kanter
            Assignee: Robert Kanter


It would be great if we could add a machine-readable output format, say JSON, to the {{mapred job -history \[all\] <jobHistoryFile>}} command so that it's easier for programs to consume that information and do further processing on it.  At the same time, we should keep the existing API and formatting intact for backwards compatibility.
