I don't think there's a CDH that includes Hadoop 1.2.1 So either your code is doing something slow or it's the reading itself. For the latter, make sure you go through http://hbase.apache.org/book.html#perf.reading and we also recently had this thread on the list were you can see some "live" performance debugging http://www.mail-archive.com/user@hbase.apache.org/msg27174.html. For example, make sure you're not running on the local job tracker.
