siddhantsangwan opened a new pull request, #5080: URL: https://github.com/apache/ozone/pull/5080
## What changes were proposed in this pull request? `ECUnderReplicationHandler` checks if current available source datanodes + potential replica datanodes satisfy placement policy. If they don't, the targets are rejected and recovery fails. While this check makes some sense, it can block container recovery. Since under replication is more serious than mis replication, we should let a new replica be reconstructed even if it doesn't satisfy placement policy. Also, we should rely on the policy to suggest a node that satisfies the policy - if there is none, the policy will fallback and try to suggest a node on a rack where the container is already present. Changes: Allow recovery even if placement policy is not satisfied. Also added some logs. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-9019 ## How was this patch tested?
