Sandy Ryza commented on MAPREDUCE-5403:
---------------------------------------
Filed YARN-973 for the YARN changes. Uploading a patch with the mentioned
changes. Including the MR changes here to make reviewing easier and because
they won't stand on their own.
I noticed that there's a separate APP_CLASSPATH environment variable, which
does something else. It might make sense to rename YARN_APPLICATION_CLASSPATH
to something like YARN_FRAMEWORK_CLASSPATH? Any name suggestions welcome.
> MR changes to accommodate yarn.application.classpath being moved to the

> yarn.application.classpath is a confusing property because it is used by
> MapReduce and not YARN, and MapReduce already has
> mapreduce.application.classpath, which provides the same functionality.
