In order to change the hostname on my Cloudera single node CMS system. However, now none of my services will start. Everything is set to localhost (because its all on this one host). I notice that the old hostname is still referenced for the server...
Even though Hive, Hue, YARN, etc are all set to "localhost" for their databases my ZooKeeper server keeps thinking it's still the previous hostname.
How do I get rid of the hostname that is stuck in Cloudera Manager / ZooKeeper?
The only other thing I can think to do is remove the "Server Name override" for the ZooKeeper myid and then restart the service to see if it picks up the new hostname.
