> For the security purpose, it is nice to have a NamenodeProtocol to allow
> secondary namenodes and rebalacing processes to communicate with a primary
> namenode. In the first version the NamenodeProtocol is going to support one
> RPC:
> BlockLocations[] getBlocks(DatanodeID datanode, long size);
> This RPC allows a rebalancing process to fetch a partial blocks map from a
> namenode. It returns a list of blocks on the given datanode and its
> locations, whose total size is the given size.
