> In MR1 we have the notion of CompletedJobStatus store to aid fast responses
> to job.getStatus. We need the equivalent for MR2, an option is to add the
> jobStatus to the end of the JobHistory file to which the JHS can easily jump
> ahead to and serve the query, it should also cache this for a fair number of
> recently completed jobs.
