Matthew Bowden commented on AIRFLOW-2355:
-----------------------------------------
What [~sreenath.kamath] described is exactly what we've done at my workplace -
we ended up building a plugin to make this pushing and pulling from XComs
easier for a DAG that has SubDAGs
> Airflow trigger tag parameters in subdag
> ----------------------------------------

> Key: AIRFLOW-2355
> URL: https://issues.apache.org/jira/browse/AIRFLOW-2355
> Project: Apache Airflow
> Issue Type: Bug
> Components: api
> Affects Versions: 1.9.0
> Reporter: Mohammed Tameem
> Priority: Blocker
> Fix For: 1.9.0
>
>
> The command airflow {color:#8eb021}+_trigger_dag -c
> "\{'name':'value'}"_+{color} sends conf parameters only to the parent DAG.
> I'm using SubDags that are dependent on these parameters. And no parameters
> are recieved by the SubDag.
> From source code of SubDag operator I see that there is no way of passing
> these trigger parameters to a Subdag.
