Hi, I am new to zeppelin and just got it configured to run in my YARN cluster, but I was wondering if there is a configuration or even a hard setting that shuts down interpreters after in-activity. It seems like the interpreter (and it's yarn consumption) hang out indefinitely, ideally there would be a clean way (like logout or a shutdown button within the notebook) to shutdown these interpreters, but additionally there should be a way for an admin of zeppelin to impose and idle timeout. As a note to the scope of this, is dynamic yarn resource allocation configured (such that once a paragraph finishes it can release vcores)?
