> DeadNodeHandler should not remove replica for a dead maintenance node

> Key: HDDS-2607
> URL: https://issues.apache.org/jira/browse/HDDS-2607
> Project: Hadoop Distributed Data Store
> Issue Type: Sub-task
> Components: SCM
> Affects Versions: 0.5.0
> Reporter: Stephen O'Donnell
> Assignee: Stephen O'Donnell
> Priority: Major
> Labels: pull-request-available
>
> Normally, when a node goes dead, the DeadNodeHandler removes all the
> containers and replica associated with the node from the ContainerManager.
> If a node is IN_MAINTENANCE and goes dead, then we do not want to remove its
> replica. They should remain present in the system to prevent the container
> being marked as under-replicated.
> We also need to consider the case where the node is dead, and then
> maintenance expires automatically. In that case, the replica associated with
> the node must be removed and the affected containers will become
> under-replicated.
