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).
