---------------------------------------
Summary: Airflow "test" command checks dependencies
Key: AIRFLOW-1304
URL: https://issues.apache.org/jira/browse/AIRFLOW-1304
Project: Apache Airflow
Issue Type: Bug
Affects Versions: 1.8.1
Reporter: Jakub Powierza
Priority: Minor
According to [docs|https://airflow.incubator.apache.org/cli.html] "test"
command:
{code}
(...) will run a task without checking for dependencies (...)
{code}
But as I've seen this is not true. I've recently tried to run test for one of
my task that was already in running state. It gave me this error and didn't run
at all:
