> As HBASE-19729 comment , there are following points to be optimized:
> 1. when the number of cells exceed max version in scan, we should return
> SEEK_NEXT_COL match code, but if current code is INCLUDE_AND_SEEK_NEXT_ROW,
> we can optimize to choose the max step between SEEK_NEXT_COL and
> INCLUDE_AND_SEEK_NEXT_ROW, which is SEEK_NEXT_ROW
> 2. check to call ColumnTracker#doneWithColumn() only when we change the
> match code to SEEK_NEXT_COL or INCLUDE_AND_SEEK_NEXT_COL because of
> filterResponse.
> 3. More UT for those edge case..
