The TEST_DAG_PARENT will get executed. The TEST_DAG_CHILD will get triggered but doesn't execute, not sure why. The TriggeredDagRunSensor will then timeout. Even though I don't see the typical "triggering dag" log message, I know the child dag gets triggered because when I run `airflow scheduler` the triggered child dag will execute. Another thing that makes debugging harder is that the log messages in the TriggeredDagRunSensor don't display in the nose output. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
