> 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.
