>
> MAPREDUCE-817 added an API to get the JobHistory URL from the JobTracker.
> This is useful in two ways:
> 1) Users can use this API to get the URL, copy the history files to their
> local disk, and, do processing on them
> 2) APIs like JobSubmissionProtocol.getJobCounters, can read a part of the
> history file, and then return the information to the caller (if the job is
> not there in JT memory). This would mimic most of the
> CompletedJobsStatusStore functionality.
