HDFS Ports Protocol

  • #53342

    When opening the default ports used by the various HDFS services, using the following:
    netsh advfirewall firewall add rule name=AllowRPCCommunication dir=in action= allow protocol=TCP localport=135
    does the protocol value always equal= TCP?

    For example if opening port 8020/9000 for the NameNode metadata service, is following correct?
    netsh advfirewall firewall add rule name=AllowRPCCommunication dir=in action= allow protocol=IPC localport=8020-9000

    Hi Warsame,
    By default HDFS NameNode listens on TCP port 8020 for incoming ipc requests. When your firewall is setup to allow communication on this port, this should allow the datanodes to communicate to the Namenode.
