If you open a scanner with a first row, hbase will find the first row that matches or the next one after the provided first row. To stay within a range that all adheres to a particular prefix, see the http://hadoop.apache.org/hbase/docs/r0.19.3/api/org/apache/hadoop/hbase/filter/PrefixRowFilter.html. Don't forget to wrap it in a http://hadoop.apache.org/hbase/docs/r0.19.3/api/org/apache/hadoop/hbase/filter/WhileMatchRowFilter.html. See the 'description' on this page, http://hadoop.apache.org/hbase/docs/r0.19.3/api/org/apache/hadoop/hbase/filter/package-summary.html#package_description, for why WhileMatchRowFilter is needed.
