             Summary: Delay Starting ContainerBalancer after SCM failover
                 Key: HDDS-8169
                 URL: https://issues.apache.org/jira/browse/HDDS-8169
             Project: Apache Ozone
          Issue Type: Sub-task
          Components: SCM
            Reporter: Siddhant Sangwan
             Fix For: 1.4.0


ContainerBalancer is a highly available service. It's configurations are 
replicated using protobufs and persisted on each SCM in binary. It runs only in 
the leader SCM. Currently, there is no delay when ContainerBalancer starts 
running in the new leader. We should wait for some time for Datanodes to detect 
that there's been a leader change and expire commands from old leaders.
