我试图运行水槽，我得到nullpointerexception：

我用来启动水槽的命令如下：
水槽：
./flume-ng agent --conf /home/training/Downloads/apache-flume-1.6.0-bin/conf/flume-conf.properties.template --name agent flume配置文件如下：agent . sources = seqGenSrc agent.channels = memoryChannel agent.sinks = loggerSink agent.sources.seqGenSrc.type = exec agent.sources.seqGenSrc.command = tail -F /home/training/Desktop/log.txt agent.sources.seqGenSrc.channels = memoryChannel agent.sinks.loggerSink.type = logger agent.sinks.loggerSink.channel = memoryChannel agent.channels.memoryChannel.type = memory agent.channels.memoryChannel.capacity = 100 agent.sinks.loggerSink.type = hdfs agent.sinks .loggerSink.hdfs.path = hdfs：// localhost：54310 / user / training / logs agent.sinks.loggerSink.hdfs.fileType = DataStream
能不能让我知道我错过了什么 .
在此先感谢您的回复 .

我注意到两件事：
--conf参数，但省略了--conf-file参数 . 例如，我开始像这样：./bin/flume-ng agent -Dflume.root.logger=INFO,console --conf ./conf --conf-file ./conf/test.conf --name agentloggerSink，然后将接收器的类型设置为hdfs. 我不认为设置水槽的类型两次是你想要的（或Flume想要的） .顺便说一句，我重新格式化了你的配置：
