Java Flume 1.6中的自定义水槽水槽部署

我使用的是Flume1.6，有一个自定义的接收器实现。我已经构建了一个包含所有必要依赖项的JAR文件，并将其放在

/plugins.d/MySink/lib/MySink.JAR

从阅读可用资源中可以看出，如果我将JAR文件放在plugins.d目录下，则在运行

flume ng

时，必须自动解析类路径。但是，我得到以下异常堆栈，表示无法加载接收器实现中的主类：

org.apache.flume.FlumeException:无法加载接收器类型： MySink，类：MySink

问题：我是否应该在Flume的配置文件中进行任何进一步的特定设置？将JAR文件放在目录结构下，即：

<FLUME_DIR>/plugins.d/MySink/lib/MySink.jar 

---

flume社区中没有人可以对上述问题发表意见吗？看来我分两步解决了这个问题。首先，我注意到我没有在flume配置（即com.xyz.MySink）中指明完全限定的类名。它只是conf文件中的MySink:）其次，我将MySink.jar放在/lib目录下。然后，上面的异常就消失了……毕竟，尽管flume文档中以这种方式指定了jar文件，但将jar文件放在plugins.d目录下仍然不起作用，这仍然很奇怪。请在此就此事发表评论。
