[jira] [Updated] (MAPREDUCE-6627) Add machine-readable output to mapred job -history command

     [ https://issues.apache.org/jira/browse/MAPREDUCE-6627?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Robert Kanter updated MAPREDUCE-6627:
-------------------------------------
    Attachment: json_all.txt
                json.txt

json.txt and json_all.txt show what the JSON output currently looks like (after prettifying it for human-readability).

> 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.
