Description

During the Ambari change hostname procedure, hostnames in configs when they were all uppercase are not being replaced. I think the code is converting hosts to all lowercase to do replacements. See:
https://github.com/apache/ambari/blob/trunk/ambari-server/src/main/java/org/apache/ambari/server/update/HostUpdateHelper.java#L383-L393

Appears to affect up from 2.6.1 and 2.6.2
