2) Wait for sleeper component to be up
3) Kill AM process PID
Expected behavior:
New attempt of AM will be started. The pre-existing container will keep running
Actual behavior:
Application finishes with State : FINISHED and Final-State : ENDED
New attempt was never launched
Note:
when the AM gets a SIGTERM and gracefully shuts itself down. It is shutting the
entire app down instead of letting it continue to run for another attempt
