> I had a functioning cluster with core services installed (HDFS, ZK, YARN, HBase). NameNode HA mode was enabled for HDFS and I stopped and started HDFS several times. HDFS also has 2 service configuration versions listed in the history; the initial revision and then the NameNode HA revision.
> I stopped all services and added a new service, Storm. When starting HDFS back up, the following is encountered:

> Taking a look at my HDFS history, I have a new, 3rd, service config version that I did not create. It shows that {{dfs.namenode.checkpoint.dir}} was removed.
