HBase itself won't do that, instead you could retrieve the list of KeyValues using the Result.raw[1] method, put that in a List and sort it by passing your own comparator to Collections.sort[2].

  1. http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/client/Result.html#raw()
  2. http://download.oracle.com/javase/6/docs/api/java/util/Collections.html#sort(java.util.List, java.util.Comparator)
