从flume到kafka，日志收集

  实时日志分析：

本篇文章主要测试 从flume到kafka的日志收集，storm日志分析，学习中！

flume 配置文件

#collector
collector.sources=cs
collector.sinks=ck hbaseSink
collector.channels=cc hbaseChannel

collector.sources.cs.type = exec
collector.sources.cs.command = tail -F /data/hudonglogs/self/channel.log
collector.sources.cs.channels=cc hbaseChannel

collector.channels.cc.type = memory
collector.channels.cc.capacity = 1000
collector.channels.cc.transactionCapacity = 100

collector.channels.hbaseChannel.type = memory
collector.channels.hbaseChannel.capacity = 1000
collector.channels.hbaseChannel.transactionCapacity = 100

#sink kafka
collector.sinks.ck.type = org.apache.flume.sink.kafka.KafkaSink
collector.sinks.ck.topic = logs
collector.sinks.ck.brokerList = localhost:9092
collector.sinks.ck.requiredAcks = 1
collector.sinks.ck.batchSize = 20
collector.sinks.ck.channel = cc

#hbase sink
collector.sinks.hbaseSink.type = asynchbase
collector.sinks.hbaseSink.channel = hbaseChannel
collector.sinks.hbaseSink.table = logs
collector.sinks.hbaseSink.columnFamily = content
collector.sinks.hbaseSink.batchSize = 5

 注意： flume中每一个source可以有多个channel，但是一个sink只能对应一个channel。

kafka consumer

public class KafkaConsumer extends Thread {

    ConsumerConnector connector;

    private String topic;

    public KafkaConsumer(String topic) {
        this.topic = topic;
        this.connector = Consumer.createJavaConsumerConnector(createConsumerConfig());
    }

    private ConsumerConfig createConsumerConfig() {
        Properties props = new Properties();
        props.put("zookeeper.connect", KafkaConfig.zkConnect);
        props.put("group.id", KafkaConfig.groupId);
        props.put("zookeeper.session.timeout.ms", "40000");
        props.put("zookeeper.sync.time.ms", "200");
        props.put("auto.commit.interval.ms", "1000");
        return new ConsumerConfig(props);
    }

    @Override
    public void run() {
        Map<String, Integer> topicCountMap = new HashMap<String, Integer>();
        topicCountMap.put(topic, new Integer(1));
        Map<String, List<KafkaStream<byte[], byte[]>>> consumerMap = connector.createMessageStreams(topicCountMap);
        KafkaStream<byte[], byte[]> stream = consumerMap.get(topic).get(0);
        ConsumerIterator<byte[], byte[]> it = stream.iterator();
        while (it.hasNext()) {
            System.out.println("receive：" + new String(it.next().message()));
            try {
                sleep(3000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}

启动 kafka集群， 然后启动producer，启动flume

hbase查看：

以上所有环境都是单节点部署！
