Hello Tux, Accessing a table in "random access"-manner is not the reason for randomizing keys. You will likely need to randomize your keys only for better performance during importing existed large dataset into HBase. Otherwise if you don't have insertion rate bigger than 20K records/sec I wouldn't suggest you to think about this issue. It would be great if you tell us more about your use-case.
MD5, SHA-1 or Jenkins Hash (in org.apache.hadoop.hbase.util.JenkinsHash) are all mechanisms you might consider.
