> 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.
