Report the AM of an application in the UI
-----------------------------------------
Key: MAPREDUCE-3309
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3309
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: mrv2
Affects Versions: 0.23.0
Reporter: Ramya Sunil
Fix For: 0.23.0
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.
