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

             Summary: Airflow Clear Command does not clear tasks in 
UPSTREAM_FAILED state
                 Key: AIRFLOW-1298
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1298
             Project: Apache Airflow
          Issue Type: Bug
          Components: cli
    Affects Versions: Airflow 1.8
         Environment: Ubuntu 12.04, Kernel: 3.13.0-113-generic, python 2.7.10
            Reporter: Aaditya Ramesh
            Assignee: Aaditya Ramesh
            Priority: Critical


We are unable to clear airflow tasks that are in the UPSTREAM_FAILED state 
using the command line. The fix is simple - just change `clear` function in 
models.py to also clear tasks in UPSTREAM_FAILED state, not just FAILED.
