--------------------------------------

             Summary: Support for Multiple Nameservices
                 Key: AMBARI-15507
                 URL: https://issues.apache.org/jira/browse/AMBARI-15507
             Project: Ambari
          Issue Type: Bug
    Affects Versions: trunk
            Reporter: Henning Kropp


This is an umbrella JIRA to collect issues related to the support of multiple Nameservices.

Currently all implementations in Amabari assume that {{hdfs_site\['dfs.nameservices'\]}} is
just a string defining one nameservices, while it actually defines multiple nameservices.

Multiple nameservices can be configured for exmaple to support seamless distcp between two
HA clusters. 

At least 3 issues can be experienced:
# Restart fails, because HdfsResource does not work, related to namenode_ha_utils.py
# (Blueprint) Install fails because DN's register with wrong cluster. Who do DN pick the right
Nameservice?
# Alerting is broken because it configures namservices as being one nameservice
