---------------------------------------------
Summary: Allow the Ozone Manager to dynamically reconfigure its
SCM node list (ozone.scm.nodes / ozone.scm.address) without a restart
Key: HDDS-16300
URL: https://issues.apache.org/jira/browse/HDDS-16300
Project: Apache Ozone
Issue Type: New Feature
Reporter: Mohammadhani Fouladgar
HDDS-13890 made DataNodes refresh their SCM connections without a restart, but
it only touched the DataNode heartbeat/registration path (SCMConnectionManager
+ StateContext endpoints). The OM reaches SCM through a different mechanism:
the SCMFailoverProxyProvider family, which loads the SCM list once at startup
via SCMNodeInfo.buildNodeInfo(conf) (SCMFailoverProxyProviderBase) and never
reloads. The OM does not register ozone.scm.nodes as reconfigurable, and the
proxy providers have no reload hook.
