------------------------------------
Summary: Separate ScmBlockLocationProtocol RPC identity from its
internal Java interface
Key: HDDS-17147
URL: https://issues.apache.org/jira/browse/HDDS-17147
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Chia-Chuan Ho
Assignee: Chia-Chuan Ho
Follow-up to HDDS-16243, applying the approach established in HDDS-16247.
ScmBlockLocationProtocol defines the internal Java service contract, while the
actual Hadoop RPC protocol is exposed through ScmBlockLocationProtocolPB and
ScmBlockLocationProtocolService.
Move the existing Java methods to ScmBlockLocationInternalInterface. Retain
ScmBlockLocationProtocol as an empty final class with the same fully qualified
class name to preserve the historical RPC protocol identity and
service-authorization ACL mapping.
Update implementations, callers, translators, and tracing proxies to use the
new internal interface. Preserve existing behavior, PB interfaces, protocol
names and versions, Kerberos metadata, and Protobuf definitions.
Verify the PB metadata, secure-mode authentication and authorization, SCM HA
failover, and client/server compatibility using existing test coverage where
applicable.
