> History does not store the runtime diagnostics information. JobHistoryParser tries to
blame a task. We propose to preserve the original runtime diagnostics that covers all the
cases including the job being killed. This is particularly important in the context of user-supplied
diagnostic message as in MAPREDUCE-5648.
