-----------------------------------------------------------
Patch 001-branch-2:
* Start with branch-2 patch because mixed version testing is only possible
between 2.7 and branch-2.
* There is no unit testing due to the difficulty of mixed versions of NNs and
DNs.
* Pass the JIRA test case manually between an 2.7 NN and a branch-2 DN.

> However, this is not possible when I have no control over the WebHDFS calls,
> e.g. Ambari and Hue have errors due to this.
