---------------------------------
Summary: Do not store datanode detailes in SCM pipeline db
Key: HDDS-5114
URL: https://issues.apache.org/jira/browse/HDDS-5114
Project: Apache Ozone
Issue Type: Bug
Reporter: Marton Elek
When the IP addresses of a cluster has been changed, the same datanodes will be
connected with a new ip address to the SCM. SCM assumes that the nodes are up
(which is right) and pipelines are available. But when allocateBlock is served
the persisted pipeline information is used instead of the fresh ones.
It should be enough to save the node uuid in the pipeline information and all
the other data can be excluded (ip and ports) and use the latest node
information.
