> Key: HDDS-3081
> URL: https://issues.apache.org/jira/browse/HDDS-3081
> Project: Hadoop Distributed Data Store
> Issue Type: Sub-task
> Components: SCM
> Affects Versions: 0.6.0
> Reporter: Stephen O'Donnell
> Assignee: Stephen O'Donnell
> Priority: Major
>
> In the current implementation, replication manager does not consider the
> container placement when checking if a container is healthy. Only the number
> of replicas are checked.
> Now we have network topology available, we should consider whether
> replication manager should detect and correct mis-replicated containers.
> In HDFS, the namenode will not automatically correct mis-replicated
> containers automatically, except at startup when all blocks are checked.
