Review comment:
       I see that YARN federation feature can have multiple RMs. 
   I created a high availability cluster to check my changes, and noticed that one of the
RMs (job-cluster-m-0) was listed as the host. 
   
   Is it safe to assume that YARN federation will behave similarly? Please note that I used
Hadoop 3.2.1 to test this.
