Review Comment:
I have a offline discussion with Shuang.
To prevent the race condition that the task two attempts report the shuffle
fetch failure concurrently and both true returned due these attempts are both
alive.
We will record the reported shuffle fetch failure taskIds in the stage.
Then exclude the TaskInfos that already reported shuffle fetch failure.
Thanks @RexXiong , also cc @pan3793
