A competing project is out with "intranode security" We are running secure HBase in production at Trend Micro now. And secure ZooKeeper. This is full integration with Secure HDFS and MapReduce (including auth tokens for MR), secure RPC, and policy enforcement of table/column ACLs implemented as a Coprocessor.
We have security for HBase, just not upstream. Let's get this in! The modular refactor for Maven will make it possible to do something like -Dsecurity We have updated our security branch up to current trunk here -- http://github.com/trendmicro/hbase/tree/security . You can use it with 0.20.203 or CDH3U0, just replace the Hadoop core jar in lib/. CDH3U0 also has append support so is the better choice of course. Try it out... - Andy
