> Issue HBASE-25299 is about the Scan#setRowPrefixFilter having not the expected effects when using also the setStartRow and/or setStopRow.
> The setRowPrefixFilter is intended to make setting the right startRow and stopRow for prefix scans. So it was always intended of using it instead of doing separate setStartRow and/or setStopRow calls.
> The reason for adding this to the Scan (~ 8 years ago) was that calculating the correct start and stop row for doing the very efficient prefix scan is very hard to do right.
> This function is very important in many of my applications and with issue HBASE-25299 it has now been marked as deprecated which I consider to be a very bad idea.
> I do agree the documentation can be improved on this point.
