Ray Zhang commented on HDFS-7737:
---------------------------------
Have finished prototype without replication feature, will run performance test
after bug fix and share the test result. Will compare performance with HDFS
Federation (static subtree partitioning).
> Implement distributed namenode

> Key: HDFS-7737
> URL: https://issues.apache.org/jira/browse/HDFS-7737
> Project: Hadoop HDFS
> Issue Type: New Feature
> Reporter: Ray Zhang
> Assignee: Ray Zhang
> Priority: Minor
> Attachments: Distributed Namenode.pdf, Dynamic Subtree Binary
> Partitioning Proposal.pdf, Implement Overflow Table.pdf, Replication Of Name
> Nodes.pdf
>
>
> 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
