Arun C Murthy updated MAPREDUCE-2880:
-------------------------------------

    Attachment: MAPREDUCE-2880.patch

Works! And tested on a secure cluster - thanks to Vinod for his help in debugging.

Still need to fix unit tests, but it's nice to see very simple classpaths etc. for containers.
Also adds admin java-opts, admin env etc.

> MRConstants.java refers a hard-coded version of MR AM jar. The build config works around
with a symlink. The deployment currently needs symlink workaround as well. We need to fix
this so that we can actually launch arbitrary versions of AMs.
