Uma Maheswara Rao G updated HDDS-4745:
--------------------------------------
Priority: Major (was: Critical)
> Cannot change Ratis port in existing cluster
> --------------------------------------------
>
> Key: HDDS-4745
> URL: https://issues.apache.org/jira/browse/HDDS-4745
> Project: Apache Ozone
> Issue Type: Bug
> Components: Ozone Datanode
> Reporter: Attila Doroszlai
> Priority: Major
> Labels: kubernetes
>
> 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.
