Jitendra Nath Pandey commented on HDFS-1647:
--------------------------------------------
Multiple namenodes can be specified as a comma separated list.
This patch adds two utility methods to DFSUtil class.
1. To get list of namenodes from the conf
2. To get the primary node given a conf and a secondary hostname.
getNNAddresses is moved from Namenode to DFSUtil.

Suresh Srinivas commented on HDFS-1647:
---------------------------------------
+1 for the patch.
This patch underwent lot of changes. In subsequent changes we should post more details on what has changed and how to configure federation.
Note that the existing single namenode configuration will continue to work without requiring any changes in federation.

Jitendra Nath Pandey commented on HDFS-1647:
--------------------------------------------
This jira doesn't address several other configuration parameters which will need to be configured namenode specific, for example dfs.namenode.http-address. That will be handled in a separate jira.
