----------------------------------
> Running Trigger DAG test with SequentialExecutor yields error
> -------------------------------------------------------------
>
> Key: AIRFLOW-46
> URL: https://issues.apache.org/jira/browse/AIRFLOW-46
> Project: Apache Airflow
> Issue Type: Bug
> Affects Versions: Airflow 1.7.0
> Environment: virtualenv, python 2.7.9
> Reporter: Siddharth Anand
> Assignee: Siddharth Anand
> Attachments: Screenshot 2016-05-04 02.22.28.png, screenshot-1.png,

>
> On a fresh install of Airflow 1.7.0, executed the following way :
> * git checkout -b b_1.7.0rc1 1.7.0rc1
> * python setup.py develop
> * airflow initdb (against sqllite and using SequentialExecutor - delete the
> previous db file)
> * airflow webserver -d
> * airflow scheduler
> * Load examples in the airflow.cfg file and disable all but 2 via the UI as
> shown below : example_trigger_controller_dag and example_trigger_target_dag
> The controller dag will run and you will see the following line in the
> scheduler output to show it succeeded :
> {panel}
> [2016-05-04 02:11:47,680] {__init__.py:36} INFO - Using executor

> [2016-05-04 02:11:51,809] {jobs.py:516} INFO - Prioritizing 0 queued jobs
> {panel}
> However, when the target dag runs, you will see :
