Siddharth Seth commented on MAPREDUCE-4693:
-------------------------------------------
The latest patch (MAPREDUCE-4693.4.patch) looks good. +1
There's a couple of follow up tasks which may be required though. Job level
counters in case of job failure. Task.selectBestAttempt needs a fix.
> Historyserver should provide counters for failed tasks

> though they are available via the AM as long as the job is still running.
> Those counters are lost when the client needs to redirect to the
> historyserver after the job completes.
