It's a greate improvement, i am looking forward to the design. And i can help to finish some sub-tasks when i am free, and i wish it can apply to our production cluster with thousands of nodes, i will be very helpful.
Thanks a lot.

> Issue Type: New Feature
> Components: resourcemanager
> Affects Versions: 3.2.0
> Reporter: Prabhu Joseph
> Assignee: Prabhu Joseph
> Priority: Major
>
> During Failover, the RM Standby will have a lag as it has to recover from Zookeeper / FileSystem StateStore. RM HA using Ratis (Raft Protocol) can achieve Fast failover as all RMs are in sync already. This is used by Ozone - HDDS-505.
