> HFileBlock store cells sequential, current when to get a row from the block,
> it scan from the first cell until the row's cell.
> The new structure store every row's start offset with data, so it can find
> the exact row with binarySearch.
> I use EncodedSeekPerformanceTest test the performance.
> First use ycsb write 100w data, every row have only one qualifier, and
> valueLength=16B/64/256B/1k.
> Then use EncodedSeekPerformanceTest to test random read 1w or 100w row, and
> also record HFileBlock's dataSize/dataWithMetaSize in the encoding.
