Description

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.
