> In RegionScannerImpl the filters get reset during calls to nextRaw:
> {code}
> public NextState nextRaw(List<Cell> outResults, int batchLimit, long
> remainingResultSize)
> throws IOException {
> ...
> resetFilters();
> if (isFilterDoneInternal()) {
> ...
> }
> {code}
> This creates a problem when returning partial Results because filters should
> only be reset in between rows (i.e. after all of the cells for a particular
> row have been returned). If a partial Result is returned, there are still
> cells in the row that have not been evaluated yet and we should avoid
> resetting the filter since it will wipe away all state information for that
> filter.
