Question

kafka_2.10-0.8.2.0
flume 1.6

这是我的水槽配置：

    a1.sources = r1
    a1.sinks = k1
    a1.channels = c1

    a1.sources.r1.type = org.apache.flume.source.kafka.KafkaSource
    a1.sources.r1.zookeeperConnect = a2:3181
    a1.sources.r1.topic = testk
    a1.sources.r1.batchSize = 5
    a1.sources.r1.channels = c1

    a1.sinks.k1.type = logger

    a1.channels.c1.type = memory
    a1.channels.c1.capacity = 1000
    a1.channels.c1.transactionCapacity = 100

    a1.sources.r1.channels = c1
    a1.sinks.k1.channel = c1

我收到以下错误：

有人可以帮忙吗？

您可以通过向flume-env.sh文件提供zookeeper jar的路径来解决此错误。之后，只需重新启动代理，您就应该看到Kafka主题中的信息流动。

FLUME_CLASSPATH="/path/to/hadoop-2.5.0-cdh5.3.1/share/hadoop/common/lib/zookeeper-3.4.5-cdh5.3.1.jar"
