在我们的应用程序中,我们希望一次只运行一个oozie工作流程。
我们面临的问题是,与第一个工作流程的连接中断,并且由于第二个工作流程的启动。在YARN上,第一个工作流程仍在运行。
我们收到以下错误消息:
E0603 : E0603: SQL error in operation, The last packet successfully received from the server was 94,669,212 milliseconds ago. The last packet sent successfully to the server was 94,669,212 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

不知道在哪里设置“wait_timeout” /“autoReconnect”属性。
是否在oozie工作流xml中的每个操作级别设置了?
问候

根据MapR技术支持工程师Prakhar Verma的说法,您可以在代码中忽略这些无害的异常。请重新编写您的Java代码。
