Hitesh Shah commented on MAPREDUCE-2863:
----------------------------------------

Patch needs to be re-based. 

Reverted some commits to test the patch. Mostly looks good. 

One minor issue seen which can be addressed in a follow-up:
  - the error info is always in json regardless of what the client accepts.

The urls for the webapp vs the webservices are different so at some point, we 
should convert the web app urls to match the ws ones e.g 
"NM:9999/node/allApplications" vs ""NM:9999/node/apps"
