> The current Spark shuffle has some hard-coded assumptions about how shuffle 
> managers will read and write data.
> The BlockStoreShuffleFetcher.fetch method relies on the 
> ShuffleBlockFetcherIterator that assumes shuffle data is written using the 
> BlockManager.getDiskWriter method and doesn't allow for customization.
