[jira] [Updated] (HDDS-16529) Replace reflective OM follower routing with typed dispatch
[ https://issues.apache.org/jira/browse/HDDS-16529?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Chu Cheng Li updated HDDS-16529:
--------------------------------
Description:
{{HadoopRpcOMFollowerReadFailoverProxyProvider}} routes requests through {{InvocationHandler.invoke(Object, Method, Object[])}} and reflection, even though the OM protocol provides a typed {{submitRequest}} method.
Replace the reflective wrapper with a concrete {{OzoneManagerProtocolPB}} implementation to improve compile-time type checking. Preserve retry behavior, lazy connections, cleanup, and read consistency hints across failover.
