You need to tell the Get or Scan to fetch more versions. For example,
the help for the get commands gives this example:
hbase> get 't1', 'r1', {COLUMN => 'c1', TIMERANGE => [ts1, ts2],
VERSIONS => 4}
In the API you would use
http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/client/Get.html#setMaxVersions(int)
Hope this helps,
