ُThank you very much for your response. We will try this workflow and I will report back any issues encountered. What about the docs? Shouldn't it be updated to contain info about upgrading to higher versions?
Our setup: We have two HBase masters but there is no cluster replication for now. We use Ansible to provision our cluster and rolling upgrade. In the past we upgraded HBase from 1.2.7 to 1.4.12 without any issues.
