[EDIT: Solved - but I am leaving the question in case anyone else hits the strange error message]
I am upgrading a HDP cluster from 2.2 to 2.3 using a manual upgrade process.
I have reached the end and perform the final step but ambari tells me that two of my machines are not upgraded. I can't see what the problem is, nor can I fix it. Any ideas?
[root@hdp01 hdp]# ambari-server set-current --cluster-name=owalhdp --version-display-name=HDP-2.3.0.0
Using python /usr/bin/python2.6
Setting current version...
Enter Ambari Admin login: admin
Enter Ambari Admin password:
ERROR: Exiting with exit code 1.
REASON: Error during setting current version. Http status code - 500.
{
"status" : 500,
"message" : "org.apache.ambari.server.controller.spi.SystemException: Finalization failed. More details: \nSTDOUT: Begin finalizing the upgrade of cluster owalhdp to version 2.3.0.0-2557\nThe following 2 host(s) have not been upgraded to version 2.3.0.0-2557.

}
Now nothing in my manual process really tells me how to install and upgrade the Stack Version on individual hosts so I am at a loss for what to do.
