我使用ApacheFlum1.4.0收集日志文件(auth.log)并存储在HDFS (Hadoop2.6.0)中。使用的命令是:
bin/flume-ng agent --conf ./conf/ -f flume.conf -Dflume.root.logger=DEBUG,console -n agentflume.conf文件包含以下内容:
agent.channels.memory-channel.type = memory
agent.sources.tail-source.type = exec
agent.sources.tail-source.command = tail -F /var/log/auth.log
agent.sources.tail-source.channels = memory-channel
agent.sinks.log-sink.channel = memory-channel
agent.sinks.log-sink.type = logger
agent.sinks.hdfs-sink.channel = memory-channel
agent.sinks.hdfs-sink.type = hdfs
agent.sinks.hdfs-sink.hdfs.path = hdfs://localhost:54310/usr/auth.log
agent.sinks.hdfs-sink.hdfs.fileType = DataStream
agent.channels = memory-channel
agent.sources = tail-source
agent.sinks = log-sink hdfs-sink运行该命令后,以下消息在循环中不断重复:
(conf-file-poller-0) [DEBUG - org.apache.flume.node.PollingPropertiesFileConfigurationProvider$FileWatcherRunnable.run(PollingPropertiesFileConfigurationProvider.java:126)] Checking file:flume.conf for changes可能是什么原因?

默认情况下,Flume设计为每30秒检查一次(这是硬编码),以查找更改的配置文件。然后重新创建受影响的组件(源、接收器或通道),以便应用新的配置。如果要禁用此行为,只需使用--no-reload-conf选项启动代理即可。
