…inator should abort stage when committed file not consistent with task status Revert apache#36564 According to discuss apache#36564 (comment) When spark commit task will commit to committedTaskPath `${outputpath}/_temporary//${appAttempId}/${taskId}` So in apache#36564 's case, since before apache#38980, each task's job id's date is not the same, when the task writes data success but fails to send back TaskSuccess RPC, the task rerun will commit to a different committedTaskPath then causing data duplicated. After apache#38980, for the same task's different attempts, the TaskId is the same now, when re-run task commit, will commit to the same committedTaskPath, and hadoop CommitProtocol will handle such case then data won't be duplicated. Note: The taskAttemptPath is not same since in the path contains the taskAttemptId. No need anymore No Existed UT No Closes apache#46696 from AngersZhuuuu/SPARK-48292.
