Suresh Srinivas commented on HADOOP-7455:
-----------------------------------------

The protocol interface that is being added is based on subset of functionality described in http://www.opencf.org/cgi-bin/viewcvs.cgi/specs/ra/resource-agent-api.txt?rev=HEAD.

Of the OCF functionality monitor, promote and demote is added. This interface will be used for building Namenode HA functionality.
