If your row keys are sorted in a lexicographical way (padded with zeroes in your case since it's longs) then simply use a scanner:
http://hadoop.apache.org/hbase/docs/r0.20.3/api/org/apache/hadoop/hbase/client/Scan.html Configure it with a start and end row key, configure setCaching to the number of rows you need and it will do a single RPC to fetch everything very efficiently. The exact response time depends on your hardware, caching, and data size.
