   > You are using logging module improperly. By `logging,info` (and similar) you are logging stuff to "root" logger:

   > Instead you should log message to "airflow.task" logger if you want messages to show up in task log:

   > logger = logging.getLogger("airflow.task")

   Actually I have tried to use logger `airflow.task`, but also failed

   Moreover, considering the level and handler of `root` logger are replaced with the level and handler of `airflow.task` logger, I think they should work same in task operators.
