---------------------------------------
Summary: Change replication logic to use PersistedOpState
Key: HDDS-3361
URL: https://issues.apache.org/jira/browse/HDDS-3361
Project: Hadoop Distributed Data Store
Issue Type: Sub-task
Components: SCM
Affects Versions: 0.6.0
Reporter: Stephen O'Donnell
Assignee: Stephen O'Donnell
In an earlier change, we decided that the Datanode would change the state of
decommissioning / maintenance replicas and report the new state in its
container report. Using that assumption, the logic in replication manager was
changed to expect the ContainerReplica to contain the decom / maintenance state.
However in HDDS-2592 it was decided that the DN would simply store the
operational state and report only the operation state in the heartbeat. This
state is reported back to SCM and stored in the datanodeDetails instances.
This means that earlier assumption (ContainerReplica will contain the decom
state) is no longer valid.
This Jira is to change the logic so replication decisions are based on the
"persistedOpState" in the datanode details object instead.
