Mikhail Antonov commented on HBASE-11241:
-----------------------------------------

The primary has been moving towards active-active vs active-backup master architecture.

I don't work on it that now.

I would also check HBASE-11165 - (Scaling to 1 million regions) - this umbrella jira and some of it's subtasks have interesting discussions, benchmarks and design docs, which kind of help to shape approach to master architecture.

> In light of discussions and refactoring progress around consensus base replication (see HBASE-10909) the concept of multiple active replicas can be applied to the HMaster entity. 
> In order to achieve this, a number of steps expressed in the subtasks of this ticket will have to be completed. similarly to HBASE-10909).
