Steve Loughran commented on YARN-4275:
--------------------------------------

This is a duplicate of YARN-1565 —please, always do a search of JIRA before filing new patches.
Not just for the history, but because the older ones have more watchers.

Being the later patch, I'm closing this one, then assigning the older one to you. Submit your
patch there and we'll start the review process.

> 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.
