We are considering to upgrade our hbase cluster from version 0.94.6 to 0.96.0 once 0.96.0 is out.
I want to know whether any possible failure may happen during the upgrade progress, and if it does happen, is it possible to downgrade to 0.94.6? Is there any best practice of upgrading 0.94.x to 0.96.0? Many thanks. ---------------------------- Best Wishes
