    Description

      When an executor is removed, tasks on other executors trying to fetch data from the lost executor run into the INPUT_READ_FAILURE. Because parent task(s) that produced the blocks lost along with the executor are guaranteed to be retried via the EXECUTOR_REMOVED event, we can simply retry just the tasks that ran into INPUT_READ_FAILURE.
