> HDDS-242 provides a new class ContainerReportHandler which could handle the
> ContainerReports from the SCMHeartbeatDispatchere.
> HDDS-228 introduces a new map to store the container -> datanode[] mapping
> HDDS-199 implements the ReplicationManager which could send commands to the
> datanodes to copy the datanode.
> To wire all these components, we need to put implementation to the
> ContainerReportHandler (created in HDDS-242).
> The ContainerReportHandler should process the new ContainerReportForDatanode
> events, update the containerStateMap and node2ContainerMap and calculate the
> missing/duplicate containers and send the ReplicateCommand to the
> ReplicateManager.
