Pradeep Subrahmanion commented on YARN-4275:
--------------------------------------------

New REST API introduced in this patch will return the default classpath if 
'yarn.application.classpath'  is not configured.
Does <rm-host>:8088/conf do the same ?. From one of the comments in issue 
YARN-2625, it doesn't return default classpath.

> Currently to build AM request, the application client need to know about the 
> YARN CLASSPATH. Application client has no way to fetch the default CLASSPATH 
> of YARN or yarn.application.classpath property in yarn-site.xml through REST 
> API.
> Introduce a new REST API to fetch yarn CLASSPATH and other system properties 
> that may be useful for those who implement REST client.
