Srimanth Gunturi commented on YARN-988:
---------------------------------------
[~hitesh], My original goal was to get MR2 specific information via API. I went
down the proxy path reading
[http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/MapredAppMasterRest.html].
How do I determine the host:port documented there? Also, once the application
has completed, there is no AM to serve the API?
If there is any API, JMX way of getting MR specific information documented in
YARN-989, please let me know.
> RM /proxy/app always gives HTML response
