Robert Parker commented on YARN-862:
------------------------------------

[~ojoshi] yes this change is not compatible with rolling upgrades, that work will be in YARN-819
which will allow version checking that will be compatible with rolling upgrades.  This change
may not be valid outside of the Yahoo! use case for current 0.23 were old version NM connects
to the new RM without note during cluster upgrades.
