> DN does not have the topology info included in its heartbeat message for
> container report/pipeline report.
> SCM is where the topology information is available. During the processing of
> heartbeat, we should not rely on the datanodedetails from report to choose
> datanodes for close container. Otherwise, all the datanode locations of
> existing container replicas will fallback to /default-rack.
>
> The fix is to retrieve the corresponding datanode locations from scm
> nodemanager, which has authoritative network topology information.
