david-streamlio opened a new pull request, #102:
URL: https://github.com/apache/pulsar-connectors/pull/102
Fixes #101
### Motivation
The HBase sink throws `java.lang.NoClassDefFoundError:
io/opentelemetry/semconv/SemanticAttributes` on its first table operation — it
cannot write in a current build.
- The version catalog pins `opentelemetry-semconv = 1.37.0`.
- `hbase-client` 2.6.4 requests `semconv:1.29.0-alpha`, but the enforced
platform force-upgrades it to 1.37.0 on `:hbase:runtimeClasspath`.
- `SemanticAttributes` was removed from semconv after the ~1.30 line —
confirmed absent from the 1.37.0 jar.
- HBase references that class while building a trace span on **every** table
op, so the missing class surfaces as `NoClassDefFoundError` on the first
`put`/`get`/`createTable`.
Same shape as the Aerospike (#97) and Canal (#99) findings: compiles and
packages fine, non-functional at runtime because the platform resolves a
dependency the client library can't use. Found while attempting HBase
integration coverage (#51).
### Modifications
```kotlin
pulsarConnectorsDependencies {
exclude(libs.opentelemetry.semconv)
}
dependencies {
// ...
implementation("io.opentelemetry.semconv:opentelemetry-semconv:1.29.0-alpha")
}
```
### Verifying this change
```
# resolved semconv on :hbase:runtimeClasspath after the change:
io.opentelemetry.semconv:opentelemetry-semconv:1.29.0-alpha
# SemanticAttributes.class present in that jar: 1 (was 0 in 1.37.0)
```
Existing `:hbase:test` suite still passes. `:hbase:compileJava` clean.
### Caveat
Proven on the module's **resolved dependencies** — the class the sink needs
is now on the classpath. Not yet verified against NAR classloading in a live
Pulsar broker; the runtime write path is exercised by the integration test in
#51, which is separately blocked on environment issues. This dependency fix
stands on its own regardless.
