Yes, I meant HBase. I am just getting into this so was confused and am clear now. Thanks, Dean

You'll have to read up on HBase replication (which has been added to trunk fairly recently) or model your problem around the capabilities of our Rowlog library, as far as I can guess what you're aiming at. * http://hbase.apache.org/docs/r0.89.20100726/replication.html * http://outerthought.org/blog/449-ot.html The use of 'Hadoop' instead of 'HBase' in your question confuses me a bit though.
