Hi Genius, I understand that we use the command to start namenode and datanode. But I don't know how HDFS starts client side and creates the Client side object(Like DistributedFileSystem), and client side RPC server? Could you please point it out how HDFS start the client side dameon? If the client side uses the same RPC server with server side, Can I understand that the client side has to be located at either Namenode or Datanode?
Thanks so much. Kun
