> 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.

> back up, the following is encountered:
