ncanis commented on HBASE-3459:
-------------------------------

we will behave the same way by using ValueFilter and PageFilter
{code}
                FilterList list = new FilterList();
		ValueFilter valueFilter = new ValueFilter(CompareOp.EQUAL, new BinaryComparator(value));
		PageFilter rowFilter = new PageFilter(1);
		list.addFilter(valueFilter);
		list.addFilter(rowFilter);

{code}
