Summary: EC: Validate replication config at server-side
Key: HDDS-8273
URL: https://issues.apache.org/jira/browse/HDDS-8273
Project: Apache Ozone
Issue Type: Sub-task
Components: Ozone Manager
Reporter: Stephen O'Donnell
Assignee: Attila Doroszlai
Replication config validation is all client side. Looking for usages of
{{ReplicationConfigValidator.validate()}}, it is used when the config is parsed
from the string form, and then it is used in {{RPCClient.createKey()}} to
validate the RepConfig object, but it does not seem to be validated server side.
I think we should add a validation in OM's createKey to enforce the rule at the
server side, as it would be possible for a user to change the client side
config and then submit keys with any repConfig without the admin being aware of
it.
At least if we have a rule at the server side, someone has to make a decision
to adjust the rule and restart OM for it to take effect.
