> Project: Apache Ozone
> Issue Type: Bug
> Reporter: Pratyush Bhatt

> *Scenario:* Stop a DN from the pipeline and check re-replication.
> *Steps:*
> 1. Do a key put.
> 2. List all the replica DNs.
> 3. Stop one of the DN.
> 4. Do "ozone debug chuninfo" command.
> *Configs:*
> {code:java}
> "hdds.scm.replication.thread.interval": "5m",
> "ozone.scm.stale.node.interval": "2m",
> "ozone.scm.dead.node.interval": "4m", {code}
> *Observed behavior:*
> The command is throwing _ERROR scm.XceiverClientGrpc: Failed to execute command GetBlock_ and it lists only 1 Keylocation(sometimes 0).
> {code:java}
