Fei Hui commented on HDFS-13293:
--------------------------------
[~elgoiri] ClientProtocol code about addBlock is following
{code:java}
LocatedBlock addBlock(String src, String clientName,
ExtendedBlock previous, DatanodeInfo[] excludeNodes, long fileId,
String[] favoredNodes, EnumSet<AddBlockFlag> addBlockFlags)
throws IOException;
{code}
Maybe RBF can resolve hdfs locality with the favoredNodes parameter.
> RBF: The RouterRPCServer should transfer CallerContext and client ip to
> NamenodeRpcServer
