Yarn autorestart failed application

Question

We've a streaming application running on yarn and we would like to ensure that is up running 24/7.

Is there a way to tell yarn to automatically restart a specific application on failure?

Answer 1

Have you tried Hadoop Yarn - ResourceManger Restart

Yarn will restart the driver if this fails with the feature “yarn.resourcemanager.am.max-attempts”, and by default it’s 2.

Answer 2

You can specify the max attempt of a specific application using ApplicationSubmissionContext::setMaxAppAttempts Here is the document for this function
