Ankit Singhal commented on HBASE-19696:
---------------------------------------
Thank you guys for the review.
bq. BTW, I have another unrelated problem: when filterResponse is
INCLUDE_AND_SEEK_NEXT_ROW and matchCode is INCLUDE_AND_NEXT_COL, we should
return INCLUDE_AND_SEEK_NEXT_ROW. but the current code will return
INCLUDE_AND_NEXT_COL, seems like it can be optimized ?
Yes [~openinx], you are right, have taken care this as well in the new patch.
> Filter returning INCLUDE_AND_NEXT_COL doesn't skip remaining versions when
> scan has explicit columns

> INCLUDE_AND_NEXT_COL from filter doesn't skip remaining versions of the cell
> if the scan has explicit columns.
> This is because we use a column hint from a column tracker to prepare a cell
> for seeking to next column but we are not updating column tracker with next
> column when filter returns INCLUDE_AND_NEXT_COL.
