Replicating a standalone HBase 0.2 deployment

As far as I'm aware the current stable release of HBase, 0.2, does not support replication, although it is being built into the next version.

How would you recommend replicating a standalone (non-distributed) deployment of HBase (0.2) ?

I want the secondary instance to be used as a working backup i.e. read-only. I can aff开发者_如何学编程ord asynchronous backups with "eventual consistency", and a small amount of loss (the data is non-critical).

So far my only thought was to manually update the secondary instance, asynchronously, after writing to the primary instance.

HBase natively tolerates node failure/failover (assuming that you are running on HDFS), so it's not really necessary to maintain a replica like you would with a RDBMS.

What's wrong with just using HDFS replication?

EDIT: In this case, you would switch from standalone to distributed, and just have 2 nodes with a replication factor of 2.
