John- That fixed it. Not only did each of the zoo.cfg files not contain the server.x lines, they each had the same id in their myid file. They didn't know about each other at all.
Once I read the entry on server.x in the Zookeeper Administrator's Guide (http://zookeeper.apache.org/doc/r3.1.2/zookeeperAdmin.html#sc_configuration) it all made sense. Thanks for the assist.

I confirmed that all of my accumulo-site.xml files have the same list of Zookeeper instances for instance.zookeeper.host. So that led me to wonder about consistency. I decided to see if all of the Zookeeper nodes match. They don't. Two of the zookeeper nodes do not have any /accumulo path. One does. So Accumulo must be answering based on one or both of the Zookeeper nodes that do not have a /accumulo path and not based on the one with the path. I'm not sure how Zookeeper got into this state. Any ideas on how to fix it?

If you have accumulo-site.xml pointing at a different set of ZooKeepers you will see the behavior your experiencing.

Executing an ls /accumulo/instances using zkCli.sh I can see two instances listed. Using bin/accumulo org.apache.accumulo.server.util.ListInstances I see none listed. I'm running CDH4.3 and Accumulo 1.4.3. Josh
