Summary: OzoneContainer: expose OM RPC for OzoneClient / ofs tests
Key: HDDS-16111
URL: https://issues.apache.org/jira/browse/HDDS-16111
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Huang Kuan Hao
Assignee: Huang Kuan Hao
{\{OzoneContainer}} only exposes the S3 Gateway port (\{{9878}}), so tests can
reach Ozone only through the S3 API. Support \{{OzoneClient}} / \{{ofs://}} by
exposing the OM RPC endpoint.
- Expose OM RPC (\{{9862}}) (and SCM client \{{9860}} if needed) via
\{{withExposedPorts}}
- Add \{{getOmEndpoint()}}, and a \{{getConfiguration()}} returning an
\{{OzoneConfiguration}} (or \{{ofs://}} URI) pointing at the container
- Set \{{hdds.datanode.use.datanode.hostname=true}} and a host-reachable
\{{hdds.datanode.hostname}} so the client can reach the datanode for block IO,
analogous to \{{dfs.datanode.use.datanode.hostname}}; needs a fixed mapping for
the datanode data port
- Add a smoke test that writes and reads a key back via \{{OzoneClient}} (or
\{{ofs}}), exercising block IO, not just metadata
Note: OM returns block locations with the datanode's container-internal
address,which is unreachable from the host by default — the datanode-hostname
config above is the load-bearing part.
