我是使用Flume和Hadoop的新手，所以我正试图设置最简单（但有些帮助/现实）的例子。我在VM客户端中使用HortonWorks Sandbox。在完成一个教程12（涉及设置和使用Flume）后，一切似乎都正常工作。
所以我设置了自己应该
的flume.conf足够简单吧？这是我的conf文件
agent.sources=exec-source
agent.sinks=hdfs-sink
agent.channels=ch1
agent.sources.exec-source.type=exec
agent.sources.exec-source.command=tail -F /var/log/httpd/access_log
agent.sinks.hdfs-sink.type=hdfs
agent.sinks.hdfs-sink.hdfs.path=/flume/events
agent.sinks.hdfs-sink.hdfs.filePrefix=apacheaccess
agent.sinks.hdfs-sink.hdfs.rollInterval=10
agent.sinks.hdfs-sink.hdfs.rollSize=0
agent.channels.ch1.type=memory
agent.channels.ch1.capacity=1000
agent.sources.exec-source.channels=ch1
agent.sinks.hdfs-sink.channel=ch1
我看到有几个人在写入HDFS时遇到了问题，而且在大多数情况下，没有足够的日志来填充HDFS块。但是，rollInterval = 10应该每10秒生成一个新文件，只要至少写入1行。我可以在另一个窗口中运行“tail -F / var / log / httpd / access_log”并看到相当一致地写入日志的行，所以我认为不是这样。
这是尝试启动此代理的命令/输出

现在在这一点上我意识到我错过了几件事。
1) I expect to see something along the lines of "INFO instrumentation.MonitoredCounterGroup: Component type: SINK, name: hdfs-sink started" as my last line, which I don't
2) If I use the command “hadoop fs -lsr /flume” I should see new logs in my HDFS, but I don't. The last logs are from 8/28/2013, when I did the tutorial.
我也不希望在那里看到那条WARN线，但我不确定它为什么会存在，所以也许这就是我的问题，有人可以告诉我原因。
所以我的问题是：
1) Can anyone tell me what might be going wrong here?
2) When I get this problem sorted out, is there anything else I should be looking for to see what Flume is working correctly, reading what it should and writing to where it should and when?

当然，答案是在配置文件中启动与代理名称相同的代理时命名代理。所以我的命令行应该已经结束了“-n agent”而不是“-n apache-agent”，因为我的flume.conf文件指定了“agent.X”
之后，一切似乎都有效。

在您指定的配置文件中
agent.sources=exec-source
agent.sinks=hdfs-sink
agent.channels=ch1
因此代理商名称是代理商＆＃39; flume期望在运行flume-agent时你应该使用配置文件中指定的相同名称，所以命令应该是
/usr/lib/flume/bin/flume-ng agent -n agent
