yifeih commented on issue #24462: [SPARK-26268][CORE] Do not resubmit tasks when executors are lost URL: https://github.com/apache/spark/pull/24462#issuecomment-509437730 Actually, I think how it would work with the shuffle storage API is that you now return `Option.empty` from the `ShuffleWriter` instead of the `BlockManagerId` to denote that the shuffle file doesn't live on an executor. Then, the `removeExecutorAndUnregisterOutputs()` function won't be able to find any shuffle files that exist on the executor. This branch contains the most up-to-date version of the API and how it integrates with the rest of Spark if you want to take a look: https://github.com/palantir/spark/tree/yh/attempt-id-bmAddr
