Imagine an error or exception occurs while running the Spring Boot Yarn container, and we need to kill container from itself and return an error code.
You can use @OnContainerStart annotation as mentioned in this article: https://mchesnavsky.tech/how-to-set-up-exit-code-on-spring-boot-yarn-container.
But if we need to stop the container immediately, we just need to call:
System.exit(1);– where parameter is the error code. The container will immediately stop, and the specified error code will be sent to the AppMaster.
P.S. if you receive another error code in AppMaster, read the article carefully: https://mchesnavsky.tech/why-the-appmaster-receives-a-different-error-code-from-the-container-spring-boot-yarn.
