Subject [jira] [Created] (AIRFLOW-66) Document DAG and Task state cycle
Date Fri, 06 May 2016 23:19:12 GMT
Lance Norskog created AIRFLOW-66:
------------------------------------

             Summary: Document DAG and Task state cycle
                 Key: AIRFLOW-66
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-66
             Project: Apache Airflow
          Issue Type: Improvement
          Components: project-management
            Reporter: Lance Norskog
            Priority: Minor


There is no central description of the state sequences for DAGs and Tasks. Please create a
diagram of the state sequences and a definitive text description of each state. 

This type of documentation is useful for beginners. It is also useful as reference for when
the devs discuss subtle changes to the behavior of DAG and Task execution.

(I just now asked on the mailing list to find out what 'shutdown' state means, and it was
suggested this would be a good newbie JIRA.)
