> Currently, the Zookeeper-based state stores of RM, YARN Federation, and HDFS 
> Federation use the same ZK address config `{{{}hadoop.zk.address`{}}}. But in 
> our production environment, we hope that different services can use different 
> ZKs to avoid mutual influence.
> This jira adds separate ZK address configs for each service.
