Bibin A Chundatt commented on YARN-5597:
----------------------------------------

[~subru]

IIUC we have option of using Zookeeper as federation store and zookeeper as Resourcemanager State Store.
In 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 if 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.
