Arun Kumar M updated KNOX-3473:
-------------------------------
Description:
*Summary*
Add upstream Knox support for Livy for Spark 4 (role: LIVY_FOR_SPARK4).
*Depends on*
KNOX-3472 (livy_for_spark3) — mirror the same structure with Spark 4 naming.
*Implementation*
Mirror livy_for_spark3 with these identifiers:
| Item | Value |
|------|-------|
| Service role | LIVY_FOR_SPARK4 |
| Service name / URL path | livy_for_spark4 |
| CM service type | LIVY_FOR_SPARK4 |
| CM role type | LIVY_SERVER_FOR_SPARK4 |
| Discovery class | LivyForSpark4ServiceModelGenerator |
| Dispatch | org.apache.knox.gateway.livy.LivyDispatch |
| Icon | livyserver.png (same as Spark 3) |
*Scope (parallel file set to KNOX-3472)*
- gateway-service-definitions/services/livy_for_spark4/0.6.0/service.xml +
rewrite.xml
- gateway-discovery-cm/.../LivyForSpark4ServiceModelGenerator.java + unit tests
- META-INF/services ServiceModelGenerator registration
- ClouderaManagerServiceDiscoveryTest for LIVY_FOR_SPARK4
- gateway-admin-ui: add LIVY_FOR_SPARK4 to service role list
- gateway-release/home/conf/gateway-site.xml: add LIVY_FOR_SPARK4 to
x-forwarded servicename list
*Out of scope*
- Per-instance HA routing (same as KNOX-3472)
*Acceptance criteria*
- livy_for_spark4 routes correctly through Knox proxy
- CM discovery resolves LIVY_FOR_SPARK4 backend URLs
- Service visible on Knox Homepage and Admin UI descriptor wizard
- All new unit tests pass
