Xuan Gong commented on YARN-4243:
---------------------------------

Override the createConnection() in EmbeddedElectorService to add some retry, 
and create a Yarn Configuration for the maxAttempts because we have shared code 
(ActiveStandbyElector)and related configuration with HDFS ZKFC

> Add retry on establishing Zookeeper conenction in 
> EmbeddedElectorService#serviceInit

> Right now, the RM would shut down if the zk connection is down when the RM do 
> the initialization. We need to add retry on this part
