> 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.
