Question

我们可以使用特定参数生成风暴jar。但是，如果我们需要在本地和远程调试这个项目（实际上很远）？

如果它是简单的jar，我们可以调试。但是，这里我们使用以下命令部署jar： storm jar project.jar main_class_name

不确定我们如何部署风暴拓扑，以便我们可以在调试模式下执行风暴项目？

请查找更新的yaml文件，如下所示：

Answer 1

如果要进行远程调试，则需要在工作JVM中启用调试。请参阅此处以获取正确的Java标志：Remote debugging a Java application

将所有/共享主管storm.yaml中的此标志添加到条目worker.childopts（可能需要重新启动Storm群集）。 您需要确保每个主机只有一个工作人员盯着它！否则，两个JVM想要打开同一个端口，当然会有一个失败。

在Eclipse中，选择Run -> Debug Configuration并创建一个新的Remote Java Application。指定要调试的正在运行的工作JVM的主机和端口（端口必须与worker.childopts中指定的端口相同）。

Answer 2

要在各个管理员VM之间启用调试，您只需编辑storm.yaml文件并将workers.childopts条目更新为：

worker.childopts：＆＃34; -agentlib：jdwp = transport = dt_socket，server = y，suspend = n，address = 5％ID％＆＃34;

如果您的主管在6700,6701,6702等端口，这将在56700,56701,56702等上创建一个调试端口。
