{color:#172b4d}Hi,
I am trying to configure YARN Federation mode.I seem to be able to schedule to 
all nodes in my federation across each of my subclusters.

However my federation router shows both of my subclusters, but nodes from only 
a single cluster.{color}

This page is showing both of my clusters, configured with a single <8 CPU, 7GB>
