要将Flume的数据输出到HDFS、HBase或Kafka等存储系统,你可以通过配置Flume的Sink组件来实现。以下是一些常见的配置方法:
agent.sources = source1
agent.sinks = hdfs-sink
agent.channels = memory-channel
agent.sources.source1.type = ...
agent.sources.source1.channels = memory-channel
agent.sinks.hdfs-sink.type = hdfs
agent.sinks.hdfs-sink.hdfs.path = hdfs://namenode/flume
agent.sinks.hdfs-sink.hdfs.fileType = DataStream
agent.sinks.hdfs-sink.hdfs.writeFormat = Text
agent.sinks.hdfs-sink.channel = memory-channel
agent.sources = source1
agent.sinks = hbase-sink
agent.channels = memory-channel
agent.sources.source1.type = ...
agent.sources.source1.channels = memory-channel
agent.sinks.hbase-sink.type = hbase
agent.sinks.hbase-sink.table = table1
agent.sinks.hbase-sink.columnFamily = cf
agent.sinks.hbase-sink.channel = memory-channel
agent.sources = source1
agent.sinks = kafka-sink
agent.channels = memory-channel
agent.sources.source1.type = ...
agent.sources.source1.channels = memory-channel
agent.sinks.kafka-sink.type = org.apache.flume.sink.kafka.KafkaSink
agent.sinks.kafka-sink.brokerList = broker1:9092,broker2:9092
agent.sinks.kafka-sink.topic = topic1
agent.sinks.kafka-sink.channel = memory-channel
在每个配置文件中,你需要根据具体的需求和环境来配置不同的参数。配置完成后,启动Flume agent即可将数据输出到指定的存储系统中。
