Zheng Hu commented on HBASE-19696:
----------------------------------
bq. we can't return the code from getNextRowOrNextColumn(cell) as it will skip
...
Yes, It's true.
The fix seems good, [~an...@apache.org].
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 ?
The same problem when (filterResponse, matchCode) =
(INCLUDE_AND_SEEK_NEXT_ROW, INCLUDE).
> 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.
