Apache HBase Replication is a way of copying data from one HBase cluster to a different and possibly distant HBase cluster. It works on the principle that the transactions from the originating cluster are pushed to another cluster. In HBase jargon, the cluster doing the push is called the master, and the one receiving the transactions is called the slave. This push of transactions is done asynchronously, and these transactions are batched in a configurable size (default is 64MB).
