Hi, Can someone suggest how can I stop execution/mark(failed or any other status) of all sibling tasks (also can be passed as a list) if one of them failed? It's just useless for me to process other tasks if one failed, because in my case it's for sure issue with my processing soft and it will lead to fixing and recompilation of it, and in any case reprocessing all tasks with newer version. I've tried various manipulations with TaskInstances and Jobs states on on_failure_callback but nothing seem to work.
Best, Paul
