---------------------------
Summary: Add a "none_skipped" trigger rule
Key: AIRFLOW-4232
URL: https://issues.apache.org/jira/browse/AIRFLOW-4232
Project: Apache Airflow
Issue Type: New Feature
Reporter: al
Assignee: al
Fix For: 1.10.3
Add a "none_skipped" trigger rule so that downstream tasks will only run if
_all_ their upstream tasks have succeeded or failed.
Example:
* Task 1 is a transform task that creates a temp table.
* Task 2 is a cleanup task that drops the temp table.
Task 1 >> Task 2
If Task 1 succeeds or fails, Task 2 should drop the temp table as cleanup.
However if the task never runs, we should just skip it.
Or perhaps Task 2 is a logging task that only logs successes and failures, but
doesn't log skips to cut down on noise.
