Prateek Maheshwari updated SAMZA-1724:
--------------------------------------
Description:
When running in YARN, control script runs ApplicationRunnerMain to
start/stop/get status for jobs. It parses the output of the process after it
exits and looks for a particular string to check job status.
Currently ApplicationRunnerMain's main method just returns at the end of
execution. This can cause the process to get stuck (i.e. not exit) if there are
still non-daemon threads running becuase some code doesn't shut down its
executor services during shutdown.
We should directly exit with System.exit(0) at the end of main to guarantee
shutdown.
