--------------------------------
Summary: Add a link to the external task that ExternalTaskSensor
is waiting for
Key: AIRFLOW-5840
URL: https://issues.apache.org/jira/browse/AIRFLOW-5840
Project: Apache Airflow
Issue Type: Improvement
Components: operators
Affects Versions: 1.10.6
Reporter: Qian Yu
When using ExternalTaskSensor, there's no indication on the Web UI regarding
which task the sensor is waiting for. Does anyone have ideas for improving
this?
One idea is to override the get_link() abstract method of ExternalTaskSensor
and point it to the task that the sensor waits for. Maybe something like this
(just for demo, not tested and likely not working):
{code:python}
def get_link(self, operator: BaseOperator, dttm: datetime) -> str:
return
"{}?dag_id={}&task_id={}&execution_date={}".format(conf["base_url"],
self.external_task_id, self.execution_date.isoformat())
{code}
