Luke Lu commented on MAPREDUCE-2863:
------------------------------------
How about a working demo patch to add an echo service at /yarn/apps/echojson?
My patch would be just one-line as I mentioned above. The web.xml posted by
Alejandro won't even work because it'll interfere with the existing common
servlets (/stacks, /conf, /metrics, /logLevel, /jmx etc).
> Support web-services for RM & NM
