Does Monitor Display Multiple Masters?
I think the answer to this question is no, but maybe I'm overlooking
something.
In my three node cluster, I changed the conf/master file to include both
affy-master and affy-slave1. Then I ran start-all.sh. The master process is
definitely running on both nodes. The 'master' monitor page lists
affy-slave1 as the master node. Would the other masters be listed anywhere?

It could be a nice addition. The masters are all registered in Zookeeper,
however there isn't currently a method that retrieves them (see
ACCUMULO-1286).

I think you're right. I don't recall seeing that anywhere.
It would be a nice addition to have them present. It might require
masters to register in ZooKeeper (aside from the one which is currently
the master). I'm not sure off the top of my head.
