-------------------------------------

             Summary: Remove DAG.crawl_for_tasks method
                 Key: AIRFLOW-1141
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1141
             Project: Apache Airflow
          Issue Type: Task
            Reporter: Jeeyoung Kim
            Priority: Trivial


Currently {{DAG}} class has the method:

{noformat}
    def crawl_for_tasks(objects):
        """
        Typically called at the end of a script by passing globals() as a
        parameter. This allows to not explicitly add every single task to the
        dag explicitly.
        """
        raise NotImplementedError("")
{noformat}

which is not called or tested from anywhere. I suggest removing this method as it doesn't do anything and there's no documentation related to it. Moreover, if one creates a subclass of DAG, pylint returns the following warning: {{Method 'crawl_for_tasks' is abstract in class 'DAG' but is not overridden (abstract-method)}}
