--------------------------------
Summary: ReplicationManager fail to find proper node topology
based on Datanode details from heartbeat
Key: HDDS-1713
URL: https://issues.apache.org/jira/browse/HDDS-1713
Project: Hadoop Distributed Data Store
Issue Type: Sub-task
Reporter: Xiaoyu Yao
Assignee: Xiaoyu Yao
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.
