@potiuk I will check if this is getting executed twice in "normal" circumstances / complex error scenarios as you mentioned. My understanding from reading the documentation was that the failure callback has to be executed in all cases. ``` Generally speaking - yes the callback can be executed by both task running (when task CAN execute callback) and by DagFileProcessor (when task callback cannot be executed in task - for example when task was forcefully killed). ``` When the execution is failed during the run, or the task is forcefully killed, I thought a failure callback for the task will be invoked as there is no mention of this one in the documentation. I can verify this part and document it. -- This is an automated message from the Apache Git Service.
