Thank you [~subru]
Could you clarify query related to State Store usage
IIUC we have option of using Zookeeper as federation store and zookeeper as
Resourcemanager State Store.
For deployment are we suggesting to use single zookeeper instance for all the
RM subclusters (as RMStateStore) and also for FederationStateStore ?
While evaluating the store implementation of statestore + kerberos for zk
connection i find following limitation
Currently in zookeeper 3.4.6 doesn't support multiple secure zk client with
different configuration on same jvm instance.
ZOOKEEPER-2139 is included in 3.5.2 only.
