[jira] [Created] (YARN-9443) Fast RM Failover using Ratis (Raft protocol)

Prabhu Joseph created YARN-9443:
-----------------------------------

             Summary: Fast RM Failover using Ratis (Raft protocol)
                 Key: YARN-9443
                 URL: https://issues.apache.org/jira/browse/YARN-9443
             Project: Hadoop YARN
          Issue Type: New Feature
          Components: resourcemanager
    Affects Versions: 3.2.0
            Reporter: Prabhu Joseph


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.
