> Currently, the JHS has no information about jobs whose AMs have failed. This
> is because the History is written by the AM to the intermediate folder just
> before finishing, so when it fails for any reason, this information isn't
> copied there. However, it is not lost as its in the AM's staging directory.
> To make the History available in the JHS, all we need to do is have another
> mechanism to move the History from the staging directory to the intermediate
> directory. The AM also writes a "Summary" file before exiting normally,
> which is also unavailable when the AM fails.
