Till Rohrmann commented on FLINK-2366:
--------------------------------------

Great to hear [~sirinath19...@gmail.com] :-) If you take a look at the PR #1016 
on github (https://github.com/apache/flink/pull/1016) you'll find the 
definition of the SPI. Most notably the {{LeaderElectionService}} and the 
{{LeaderRetrievalService}} interfaces will be of your interest. Those are the 
services which you have to implement to add a new backend for HA.
