Jeff Sposetti created AMBARI-10982:
--------------------------------------

             Summary: Ambari support for NameNode Federation
                 Key: AMBARI-10982
                 URL: https://issues.apache.org/jira/browse/AMBARI-10982
             Project: Ambari
          Issue Type: Improvement
          Components: ambari-server
    Affects Versions: 2.0.0
            Reporter: Jeff Sposetti


Ambari needs to be able to deploy, manage and monitor HDFS Federation - with 2 or more Federated namespaces. 

*Hdfs configuration*

Each hdfs federated namespace has a namenode, and for each namespace namenode ha can be set up - allowing for multiple journal nodes and active/standby namenode for the namespace. When kerberizing, managing (start/stop/configure) , and monitoring, each namenode needs to be treated as a separate master.
