-------------------------
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 algorithm
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
