Brahma Reddy Battula commented on YARN-10246:
---------------------------------------------
[~dmmkr] thanks for reporting this. Make to sense to have different ZK
statestore for Federation.
[~subru]/[~bibinchundatt] looks you had discussed on this topic in
YARN-5597,any thoughts on this apporach..?
.[~inigoiri] this can used in HDFS router also.?
[~dmmkr] Looks you missed to update "isFederationZkCurator" in the following.
|66|this.isFederationZkCurator = true;|
> Enable Yarn Router to have a dedicated Zookeeper

> Project: Hadoop YARN
> Issue Type: Improvement
> Components: federation, router
> Reporter: D M Murali Krishna Reddy

> Currently, we have a single parameter hadoop.zk.address for Router and
> Resourcemanager, Due to this we need have FederationStateStore and
> RMStateStore on the same Zookeeper instance.
> With the above topology there can be a load on ZooKeeper, since all
> subcluster RMs will write to single ZooKeeper.
> So, If we Introduce a new configuration such as hadoop.federation.zk.address
> we can have FederationStateStore on a dedicated Zookeeper.
