[jira] [Created] (AMBARI-15064) RU/EU can't start if hosts have
name in MixedCASE in configs for NameNode, HBASE Master, ResourceManager
Alejandro Fernandez created AMBARI-15064:
--------------------------------------------
Summary: RU/EU can't start if hosts have name in MixedCASE in configs for NameNode, HBASE Master, ResourceManager
Key: AMBARI-15064
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
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.
