本文介绍使用Spark Streaming通过两种不同方式从多个Flume agent接收数据的方法。一种方式是使用单个Spark Receiver来监听多个Flume agent；另一种则是创建两个独立的Spark Receiver，分别连接到不同的Flume agent，并将接收到的数据流进行合并。

1. 利用一个spark receiver 接收多个flume agent

String host = args[0];
  int port = Integer.parseInt(args[1]);
  String host1 = args[2];
  int port1 = Integer.parseInt(args[3]);

  InetSocketAddress address1 = new InetSocketAddress(host,port);
  InetSocketAddress address2 = new InetSocketAddress(host1,port1);

  InetSocketAddress[] InetSocketAddressArray = {address1,address2};

JavaStreamingContext jssc = new JavaStreamingContext(new SparkConf().setAppName("JavaFlumeEventHandle_1"), Durations.seconds(2));
 JavaReceiverInputDStream<SparkFlumeEvent> flumeStream = FlumeUtils.createPollingStream(jssc, InetSocketAddressArray, StorageLevel.MEMORY_AND_DISK_SER_2());

2. 2个spark receiver接收多个flume agent

String host = args[0];
        int port = Integer.parseInt(args[1]);
        String host1 = args[2];
        int port1 = Integer.parseInt(args[3]);

        InetSocketAddress address1 = new InetSocketAddress(host,port);
        InetSocketAddress address2 = new InetSocketAddress(host1,port1);

        InetSocketAddress[] InetSocketAddressArray = {address1,address2};

      JavaStreamingContext jssc = new JavaStreamingContext(new SparkConf().setAppName("JavaFlumeEventHandle_1"), Durations.seconds(2));
//       JavaReceiverInputDStream<SparkFlumeEvent> flumeStream = FlumeUtils.createPollingStream(jssc, InetSocketAddressArray, StorageLevel.MEMORY_AND_DISK_SER_2());

        JavaReceiverInputDStream<SparkFlumeEvent> flumeStream = FlumeUtils.createPollingStream(jssc,host,port);
        JavaReceiverInputDStream<SparkFlumeEvent> flumeStream1 = FlumeUtils.createPollingStream(jssc, host1, port1);
        JavaDStream<SparkFlumeEvent> union = flumeStream.union(flumeStream1);
