Java 如何将自定义处理器添加到StreamSet

我在docker compose和jar文件中有一个StreamSets容器，它是根据教程创建的-

源已正确添加

将tarball提取到SDC用户libs目录，重新启动SDC，然后 您应该在阶段库中看到示例阶段：

为了将定制处理器添加到管道中，我将jar文件复制到用户实验室并重新启动docker

docker exec -it docker-hadoop_streamsets_1 bash
sudo cp -a /data/lib/. /opt/streamsets-datacollector-3.9.0/user-libs
docker restart docker-hadoop_streamsets_1

但重新启动后，我看不到新的目的地。我还尝试添加web界面，并阅读了这篇文章-

您所需要的只是

com.example-1.0-SNAPSHOT.jar

文件，它应该位于

/opt/streamsets-datacollector-3.9.0/user libs/sampleprocessor/lib

中，您能做一个

ls/opt/streamsets-datacollector-3.9.0/user libs

并将输出添加到您的问题中吗？@metadaddy刚刚添加了

bash-4.4$ ls -R /opt/streamsets-datacollector-3.9.0/user-libs/
