------------------------------------
Summary: Separate SecretKeyProtocol RPC identities from their
internal Java interfaces
Key: HDDS-17149
URL: https://issues.apache.org/jira/browse/HDDS-17149
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Chia-Chuan Ho
Assignee: Chia-Chuan Ho
Follow-up to HDDS-16246, applying the approach established in HDDS-16247.
The SecretKeyProtocol family combines internal Java service contracts with
role-specific RPC identities. The actual Hadoop RPC protocols are exposed
through SecretKeyProtocolDatanodePB, SecretKeyProtocolOmPB, and
SecretKeyProtocolScmPB, backed by SCMSecretKeyProtocolService.
Move the shared Java methods to internal interfaces, preserving the distinction
between shared key-retrieval operations and the SCM-specific checkAndRotate
operation.
Retain the existing fully qualified names of SecretKeyProtocolDatanode,
SecretKeyProtocolOm, and SecretKeyProtocolScm as empty RPC identity classes so
that their protocol names and service-authorization ACL mappings remain
unchanged.
Update implementations, callers, translators, and proxy providers to use the
internal interfaces. Preserve existing behavior, PB interfaces, protocol
versions, role-specific Kerberos metadata, and Protobuf definitions.
Verify PB metadata, authentication and authorization for each service role, key
retrieval and rotation, HA failover, and client/server compatibility using
existing test coverage where applicable.
