我正在使用 Apache Flume 1.4.0 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
运行命令后,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 ?
