+ On execution of the operator the task will up for retry when exception is
raised.
+ However if a command exists with non-zero value Airflow will not recognize

Review comment:
For some reason my comment disappeared?
This PR only document kakil answer on stackoverflow.
I did not have further commands on my script. It executed a exit(1) -
Airflow considered it to be a successful run. Only after applying kakil's
answer airflow considered this to be failure and set the task on up for retry
