循环获取 'checking flume.conf for changes'

Question

我正在使用 Apache Flume 1.4.0 来收集日志文件 (auth.log) 并存储在 HDFS (Hadoop 2.6.0) 中。使用的命令是：

 bin/flume-ng agent --conf ./conf/ -f flume.conf -Dflume.root.logger=DEBUG,console -n agent

flume.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

命令运行之后，下面的信息一直在循环重复：

(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？

Flume 默认设计为每 30 秒检查一次（这是 hardcoded）配置文件以查找更改。然后它会重新创建受影响的组件（源、接收器或通道）以应用新配置。如果您想禁用此行为，只需使用 --no-reload-conf 选项启动代理即可。
