Summary: Refactor ReplicationManager to consider maintenance states
Key: HDDS-2459
URL: https://issues.apache.org/jira/browse/HDDS-2459
Project: Hadoop Distributed Data Store
Issue Type: Sub-task
Components: SCM
Affects Versions: 0.5.0
Reporter: Stephen O'Donnell
Assignee: Stephen O'Donnell
In its current form the replication manager does not consider decommission or
maintenance states when checking if replicas are sufficiently replicated. With
the introduction of maintenance states, it needs to consider decommission and
maintenance states when deciding if blocks are over or under replicated.
It also needs to provide an API to allow the decommission manager to check if
blocks are over or under replicated, so the decommission manager can decide if
a node has completed decommission and maintenance or not.
