Robert Kanter commented on MAPREDUCE-5641:
------------------------------------------
hmm... I hadn't thought about the security of those files. Do you have any
alternatives on how to allow the JHS to have access to those files? Or to
somehow get those files into the done_intermediate dir?
> History for failed Application Masters should be made available to the Job
> History Server

> 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.
