jiangxb1987 commented on issue #25964: [SPARK-29287][Core] Add ExecutorConstructed message to tell driver which executor is ready for making offers URL: https://github.com/apache/spark/pull/25964#issuecomment-548572962 > The task allocated here may fail if the executor fails to start or cannot get heart beating to the driver in time. I think it's the desired behavior here, those tasks have never been started so it hurt nothing to mark them as failed. Adding a new event means more maintaining burden, also (although slightly) it increases the time gap between an executor is started and it actually runs some tasks.
