在我们的应用程序中，我们希望一次只运行一个oozie工作流。 我们面临着与第一个工作流的连接中断的问题，并且由于第二个工作流启动。在 YARN 上，第一个工作流仍在运行。
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.

不确定在哪里设置"wait_timeout"/"自动重新连接"属性。 它是否在 oozie 工作流 xml 中的每个操作级别设置？

根据MapR技术支持工程师Prakhar Verma的说法，您可以忽略代码中无害的这些异常。 请重写您的 Java 代码。
