Description

Log below is misleading:

"TaskSetManager.scala"

    if (successful(index)) {
      logInfo(
        s"Task ${info.id} in stage ${taskSet.id} (TID $tid) failed, " +
        "but another instance of the task has already succeeded, " +
        "so not re-queuing the task to be re-executed.")
    }

If fetch failed, the task is marked as successful in TaskSetManager:: handleFailedTask. Then log above will be printed. The successful just means task will not be scheduled any longer, not a real success.
