> RU/EU tries to resolve the hostnames for NameNode, HBASE Master, and ResourceManager by using MasterHostResolver.java, which queries configs and then JMX.
> Ambari DB stores the hostnames in all lowercase, so if the configs or JMX store the hostnames in a different case, then Ambari will throw an exception that the host could not be found.
> To fix this, convert all hostnames to lowercase.
