Date Thu, 25 May 2017 18:09:04 GMT
kraman created AIRFLOW-1246:

             Summary: Setting a Subdag  task Instance State Throws exception
                 Key: AIRFLOW-1246
             Project: Apache Airflow
          Issue Type: Bug
          Components: subdag
    Affects Versions: Airflow 1.8
            Reporter: kraman

When there is a parent dag with a subdag trying to set the task instance state of any of the
task instances in the subdag to ANY of  the states"failed,running/success" throws the before

This is nasty when running a local executor the process are not terminated and lie around
until manually killed.
