> In current code, all local blocks will be checked for corruption no matter it's big or not.  The reasons are as below:
>  # Size in FetchResult for local block is set to be 0 ([https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/storage/ShuffleBlockFetcherIterator.scala#L327)]
>  # SPARK-4105 meant to only check the small blocks(size<maxBytesInFlight/3), but for reason 1, below check will be invalid. https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/storage/ShuffleBlockFetcherIterator.scala#L420
