> For example:
> The while loop fetched 2 TsBlocks, each one has only one row.
> Then the *dataBitmapOutputStream* will finally write 2 "un-full" bitmap.
> Since rowCount is 2, the
> {code:java}
> int bitmapOccupation = (rowCount + 7) / 8{code}
> will get 1, which cannot hold all bitmaps in *dataBitmapOutputStream*
