Subject [jira] [Created] (HDFS-7737) Implement distributed namenode
Date Wed, 04 Feb 2015 21:13:35 GMT
Ray created HDFS-7737:

             Summary: Implement distributed namenode
                 Key: HDFS-7737
                 URL: https://issues.apache.org/jira/browse/HDFS-7737
             Project: Hadoop HDFS
          Issue Type: New Feature
            Reporter: Ray
            Assignee: Ray
            Priority: Minor

Try to add the following functions on HDFS:
1) Manually move metadata across different name nodes, without losing the original data locality
2) Automatically balance metadata across different name nodes with a novel subtree partition
3) Able to set a replication factor number for each name node, and each replicated name node
can balance live read/write traffic
4) All the functionalities above are highly configurable, and the administrator can decide
if he wants to use distributed name node setup or just HDFS federation
