Question

我正在使用Flume 1.6并拥有自定义接收器实现。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<FLUME_DIR>/plugins.d/MySink/lib/MySink.jar

下

据我所知，通过阅读可用资源，如果我将我的JAR文件放在plugins.d目录下，则必须在运行flume-ng时自动解析类路径。但是，我得到以下异常堆栈，说明我的接收器实现中的主类无法加载：

org.apache.flume.FlumeException：无法加载接收器类型： MySink，课程：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是不够的，即：

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

...谢谢
