[jira] [Commented] (AIRFLOW-4216) Sensors not rescheduled when root
task with 'reschedule' mode
[ https://issues.apache.org/jira/browse/AIRFLOW-4216?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16954608#comment-16954608 ]
Jannik Franz commented on AIRFLOW-4216:
---------------------------------------
[~jackjack10] This error has stopped ocurring for us when we switched to Airflow 1.10.3, so I can't really provide an example anymore.
[~dossett]'s error seems to be something else.

> Key: AIRFLOW-4216
> URL: https://issues.apache.org/jira/browse/AIRFLOW-4216
> Project: Apache Airflow
> Issue Type: Bug
> Reporter: Jannik Franz
> Priority: Major
>
> When using Sensors and having them as root tasks (such as no prior dependency task) and using mode 'reschedule' then the DAG state will be set to 'failed' and tasks won't be rescheduled.
> This is when the state of a DAG is updated it doesn't check for 'up_for_reschedule' in tasks properly and sets the state to failed.
> The expected behaviour would be to reschedule the task without failing the DAG.
