Jonathan Eagles commented on MAPREDUCE-3518:
--------------------------------------------
I appreciate your comment on public APIs. Something definitely needs to be
addressed. The difficulty lies in that the testing class needs the ability to
mock out the cluster (protected no good), but exists in a different package
(package-private no good). I have tried to address all concerns with the latest
patch. In this patch I merely add no public API or vars in CLI or JobClient.
Instead, I have created a small derived class for testing that is able to set
the protected cluster.
