--------------------------------------
Summary: Cannot change Ratis port in existing cluster
Key: HDDS-4745
URL: https://issues.apache.org/jira/browse/HDDS-4745
Project: Hadoop Distributed Data Store
Issue Type: Bug
Components: Ozone Datanode
Reporter: Attila Doroszlai
The config property {{dfs.container.ratis.ipc}} controls datanodes' Ratis port.
However, changing it in an existing cluster and restarting datanodes causes
failure, because Ratis stores peer addresses in its configuration and restores
after restart.
