Examples of com.cloudera.flume.agent.MasterRPC

com.cloudera.flume.agent.MasterRPC
This interface manages function calls between a Flume node and some set of masters. Implementing classes should translate these calls into rpc package-specific methods. Any method which throws an IOException is interpreted as having lost connection to all available masters.

  @Test
  public void testMasterChokeAddedAtFlumeNode() throws IOException {


    FlumeMaster master = new FlumeMaster(cfg);


    MasterRPC rpc = new DirectMasterRPC(master);
    FlumeNode node = new FlumeNode(rpc, false, false);
    master.getSpecMan().addChokeLimit(node.getPhysicalNodeName(), "bar", 786);


    // This method updateChokeLimitMap is the same method call in the
    // checkLogicalNodes() in the LivenessManager
