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.
