> When packaging shuffle fetch requests in ShuffleBlockFetcherIterator, there 
> are two limitations: maxBytesInFlight and maxBlocksInFlightPerAddress. 
> However, we don’t have test cases to test them both, e.g. the size limitation 
> is hit before the numBlocks limitation.
> We should add test cases in ShuffleBlockFetcherIteratorSuite to test:
>  # the size limitation is hit before the numBlocks limitation
>  # the numBlocks limitation is hit before the size limitation
