Luke Lu commented on MAPREDUCE-2863:
------------------------------------
GPL is explicitly disallowed by http://apache.org/legal/resolved.html, CDDL 1.0
is weakly allowed (binary only). Not sure about CDDL 1.1.
OTOH, there is no need to introduce Jersey as a dependency in this case, as RM
and NM is powered by a more powerful framework with Apache 2.0 license with
integrated hadoop pluggable authentication support :)
For example adding an echo web service in RM would be just a one-liner in
RmController.java:
{code}
public void echoJSON() { renderJSON($("echo")); }
{code}
which will echo "foo" as application/json with the URL
http://rm-host:port/yarn/apps/echojson?echo=foo.
> Support web-services for RM & NM
