> 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
> Labels: hdp
>
> 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.
