---------------------------------
Summary: Bracket IPv6 literals in Ratis peer addresses
Key: HDDS-15768
URL: https://issues.apache.org/jira/browse/HDDS-15768
Project: Apache Ozone
Issue Type: Bug
Reporter: Siyao Meng
Assignee: Siyao Meng
Ozone builds Ratis peer address strings by plainly concatenating a host and
port (`host + ":" + port`). When the host is an IPv6 literal (for example
`2001:db8::1`), the result `2001:db8::1:9858` is ambiguous: it cannot be
distinguished from a hostname, and neither Ratis nor gRPC can parse it. IPv6
literals must be wrapped in square brackets when combined with a port, e.g.
`[2001:db8::1]:9858`.
This affects every Ratis transport in Ozone:
- **Datanode pipelines** via `RatisHelper.toRaftPeerAddress` (used for the
`RATIS_SERVER`, `RATIS_ADMIN`, `RATIS`, and `RATIS_DATASTREAM` peer
addresses).
- **OM HA** and **SCM HA** via `NodeDetails.getRatisHostPortStr`
(consumed by `OzoneManagerRatisServer`, `SCMRatisServerImpl`, and
`SCMHAManagerImpl` when calling `RaftPeer.setAddress(...)`).
Ratis itself needs no change: `ratis-grpc` passes the peer address string
verbatim to `NettyChannelBuilder.forTarget(...)`, which accepts the bracketed
`[::1]:port` form, and Ratis's own `NetUtils.createSocketAddr`/`address2String`
are already IPv6-aware. The defect is purely that Ozone hands Ratis
unbracketed IPv6 strings.
