我有一个 SPARK 作业，它一直以退出代码 1 返回，但我无法弄清楚这个特定的退出代码是什么意思以及为什么应用程序返回此代码。这是我在节点管理器日志中看到的-

当我检查特定应用程序(和容器(的日志时，它没有返回任何特定的堆栈跟踪或错误消息。这是我在作业终止时在容器日志 (stderr( 中看到的内容。

因此，在这两个日志中，我只能看到应用程序以退出代码 1 退出。谁能告诉我这个特定的错误代码意味着什么以及 Yarn 引发此异常的可能原因？
我终于能够解决问题了。发生的事情是，我的调用 spark-submit 的 bash 脚本正在向其传递一个无效的参数。当作业启动时，名为 launch_container.sh 的脚本将使用传递给 spark-submit 的参数执行org.apache.spark.deploy.yarn.ApplicationMaster，当它的任何参数无效时，ApplicationMaster 将返回退出代码 1。
