> 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
