> URL: https://issues.apache.org/jira/browse/AMBARI-15064
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.2.0
> Reporter: Alejandro Fernandez
> Assignee: Alejandro Fernandez
> Fix For: 2.2.2
>
> Attachments: AMBARI-15064.branch-2.2.patch, AMBARI-15064.trunk.patch
>
>
> 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.
