I've created a branch to continue work on MAPREDUE-3902 since the changes
are reasonably big and intrusive. A branch should also make it easier for
others to contribute to the JIRA.
Will send out another mail at a later point for review requests, once this
is closer to completion. Meanwhile, if anyone does want to take a look at
provide feedback, that's very welcome.
(The initial commit to the branch is pretty big because it creates a copy
of the existing AppMaster).
