> The calculation of HighlyCompressedMapStatus's avgSize is incorrect. 
> Currently, it looks like "sum of small blocks / count of all non empty 
> blocks", the count of all non empty blocks not only contains small blocks, 
> which contains huge blocks number also, but we need the count of small blocks 
> only.
