Jonathan Eagles commented on MAPREDUCE-3309:
--------------------------------------------
On second thought, with much help from Vinod, AM on the JHS front can't be done
correctly since an AM restart will cause two AMs. Let's leave this info to the
per job page on the JHS and let's use MAPREDUCE-3350 to implement AM infos on
the per job page for the RM.

> Make provision to report the AM hostname of an application in the RM/JHS UI.
> It is difficult to trace back the AM on which an app ran when there are 100+
> jobs in history. Digging through the logs is an option but since there is no
> consistency maintained in naming of apps in UI/logs/local dirs
> (MAPREDUCE-2793), debugging is all the more harder.
