Question

我正在尝试使用dynatrace作为水槽的源和hadoop作为接收器，其中dynatrace和flume在同一台服务器上，hadoop在另一台服务器上。

但是，当开始使用水槽时，我会收到以下错误：

错误[conf-file-poller-0] （org.apache.flume.conf.file.AbstractFileConfigurationProvider $ FileWatcherRunnable.run：211） - 未处理的错误java.lang.NoSuchMethodError：org.slf4j.spi.LocationAwareLogger.log（Lorg / slf4j / Marker; Ljava / lang / String; ILjava / lang / String; Ljava / lang / Throwable;）V 在 org.apache.commons.logging.impl.SLF4JLocationAwareLog.debug（SLF4JLocationAwareLog.java:120）在 org.apache.hadoop.metrics2.impl.MetricsSystemImpl.register（MetricsSystemImpl.java:220）在 org.apache.hadoop.metrics2.MetricsSystem.register（MetricsSystem.java:54）在 org.apache.hadoop.security.UserGroupInformation $ UgiMetrics.create（UserGroupInformation.java:106）在 org.apache.hadoop.security.UserGroupInformation。（UserGroupInformation.java:208）在 org.apache.flume.sink.hdfs.HDFSEventSink.authenticate（HDFSEventSink.java:529）在 org.apache.flume.sink.hdfs.HDFSEventSink.configure（HDFSEventSink.java:247）在 org.apache.flume.conf.Configurables.configure（Configurables.java:41）在 org.apache.flume.conf.properties.PropertiesFileConfigurationProvider.loadSinks（PropertiesFileConfigurationProvider.java:373）在 org.apache.flume.conf.properties.PropertiesFileConfigurationProvider.load（PropertiesFileConfigurationProvider.java:223）在 org.apache.flume.conf.file.AbstractFileConfigurationProvider.doLoad（AbstractFileConfigurationProvider.java:123）在 org.apache.flume.conf.file.AbstractFileConfigurationProvider.access $ 300（AbstractFileConfigurationProvider.java:38）在 org.apache.flume.conf.file.AbstractFileConfigurationProvider $ FileWatcherRunnable.run（AbstractFileConfigurationProvider.java:202）在 java.util.concurrent.Executors $ RunnableAdapter.call（Executors.java:471） at java.util.concurrent.FutureTask.runAndReset（FutureTask.java:304）在 java.util.concurrent.ScheduledThreadPoolExecutor中的$ ScheduledFutureTask.access $ 301（ScheduledThreadPoolExecutor.java:178）在 java.util.concurrent.ScheduledThreadPoolExecutor中的$ ScheduledFutureTask.run（ScheduledThreadPoolExecutor.java:293）在 java.util.concurrent.ThreadPoolExecutor.runWorker（ThreadPoolExecutor.java:1145）在 java.util.concurrent.ThreadPoolExecutor中的$ Worker.run（ThreadPoolExecutor.java:615）在java.lang.Thread.run（Thread.java:745）

这是我的水槽配置文件：

请帮助。

似乎我们的其中一个用户遇到了类似的问题。他们通过使用protobuf 2.5重新编译Flume来解决问题。不要复制他们在我们的dynatrace社区论坛上发布的内容，而是可以在这里查看他们的帖子：https://community.compuwareapm.com/community/display/DL/Big+Data+Business+Transaction+Bridge?focusedCommentId=192087283#comment-192087283
