Siddhant Sangwan created HDDS-9591:
--------------------------------------
Summary: Replication Manager could incorrectly use QUASI_CLOSED
replicas as replication sources for CLOSED containers
Key: HDDS-9591
URL: https://issues.apache.org/jira/browse/HDDS-9591
Project: Apache Ozone
Issue Type: Sub-task
Components: SCM
Reporter: Siddhant Sangwan
Even though:
1. The new RM will send close commands to QUASI_CLOSED replicas of CLOSED
containers with matching sequence IDs (MismatchedReplicasHandler), and
2. It'll only replicate replicas that match the container's sequence ID
(RatisUnderReplicationHandler)
there's a chance that RM ends up replicating a QUASI_CLOSED replica of a CLOSED
container when other CLOSED replicas are available. This jira aims to fix this.
