我一直在使用hadoop 2.4.1和flume 1.5.0.1进行实验并且对这些很新。所有hadoop库都包含在$ HADOOP_HOME / share / * .jar的类路径中。我有flume-conf.properties如下：
agentMe.channels = memory-channel
agentMe.sources = my-source
agentMe.sinks = log-sink hdfs-sink
agentMe.channels.memory-channel.type = memory
agentMe.channels.memory-channel.capacity = 1000
agentMe.channels.memory-channel.transactionCapacity = 100
agentMe.sources.my-source.type = syslogtcp
#agentMe.sources.my-source.bind = 192.168.X.X
agentMe.sources.my-source.port = 8100
agentMe.sources.my-source.channels = memory-channel
# Define a sink that outputs to logger.
agentMe.sinks.log-sink.channel = memory-channel
agentMe.sinks.log-sink.type = logger
# Define a sink that outputs to hdfs.
agentMe.sinks.hdfs-sink.channel = memory-channel
agentMe.sinks.hdfs-sink.type = hdfs
agentMe.sinks.hdfs-sink.hdfs.path = hdfs://localhost:54310/user/name/science
agentMe.sinks.hdfs-sink.hdfs.fileType = DataStream
agentMe.sinks.hdfs-sink.hdfs.batchSize = 2
agentMe.sinks.hdfs-sink.hdfs.rollCount = 0
agentMe.sinks.hdfs-sink.hdfs.rollSize = 0
agentMe.sinks.hdfs-sink.hdfs.rollInterval = 3
agentMe.sinks.hdfs-sink.hdfs.writeFormat = Text
尝试从下面的代码到安装了水槽的系统进行简单的远程调用
public class FlumeClient {
public static void main(String[] args) {
MyRpcClientFacade client = new MyRpcClientFacade();
// Initialize client with the remote Flume agent's host and port
client.init("192.168.X.X", 8100);
String sampleData = "Hello Flume ...!";
for (int i = 0; i < 10; i++) {
client.sendDataToFlume(sampleData);
}
client.cleanUp();
}
}
import java.nio.charset.Charset;
import org.apache.flume.Event;
import org.apache.flume.EventDeliveryException;
import org.apache.flume.api.RpcClient;
import org.apache.flume.api.RpcClientFactory;
import org.apache.flume.event.EventBuilder;
public class MyRpcClientFacade {
private RpcClient client;
private String hostname;
private int port;
public void init(String hostname, int port) {
// Setup the RPC connection
this.hostname = hostname;
this.port = port;
this.client = RpcClientFactory.getDefaultInstance(hostname, port);
}
public void sendDataToFlume(String data) {
// Create a Flume Event object that encapsulates the sample data
Event event = EventBuilder.withBody(data, Charset.forName("UTF-8"));
// Send the event
try {
client.append(event);
} catch (EventDeliveryException e) {
// clean up and recreate the client
client.close();
client = null;
client = RpcClientFactory.getDefaultInstance(hostname, port);
}
}
public void cleanUp() {
// Close the RPC connection
client.close();
}
}
当我拨打电话时，呼叫失败并出现以下异常：
