[fix][COM][dist] Fix Spring Boot 2.7 deployment compatibility and transitive dependency issues

[aiceflower]

What changes were proposed in this pull request?

This PR fixes multiple deployment-blocking issues discovered when building and deploying the current master branch with Spring Boot 2.7. Each fix addresses a distinct failure observed during mvn package -Papache and the subsequent service startup:

1. snakeyaml 被错误排除导致服务启动失败 (63966cfb0)

   • linkis-commons/linkis-module/pom.xml / linkis-eureka/pom.xml
   • Add snakeyaml back as an explicit compile dependency. The exclusion inherited from spring-boot-starter left Eureka/Manager unable to start (Spring needs snakeyaml to parse application.yml).

2. 排除错误的传递依赖 jackson-module-scala_2.11 和 hadoop-hdfs-2.7.2 (f605e7142)

   • linkis-dist/pom.xml / linkis-dist/src/main/assembly/distribution.xml
   • Exclude jackson-module-scala_2.11 (Scala 2.11 binary, conflicts with the 2.12 the project uses) and hadoop-hdfs 2.7.2 (legacy Hadoop 2.x artifact that overrides hadoop-hdfs-client 3.3.4 and triggers NoClassDefFoundError on HDFS writes).

3. 补全 Spring Boot 2.7 部署兼容性配置 (a77d0e328)

   • linkis-dist/pom.xml: add explicit commons-lang:2.6 (Eureka Client depends on its ExceptionUtils but spring-cloud-netflix no longer pulls it transitively).
   • linkis-dist/package/conf/application-engineconn.yml: add the missing Spring Boot 2.7 compatibility keys (spring.main.allow-circular-references, spring.mvc.pathmatch.matching-strategy: ant_path_matcher, spring.mvc.servlet.path, spring.cloud.loadbalancer.cache.enabled: false). The sibling application-eureka.yml and application-linkis.yml already had these on master, but the engineconn yml was missed.

4. 修复 impala 引擎编译失败 (slf4j-api 缺失) (ee5a186c1)

   • linkis-engineconn-plugins/impala/pom.xml
   • Add slf4j-api as an explicit dependency. Without it, ImpalaEngineConnExecutor.scala fails to compile with Symbol 'type org.slf4j.Logger' is missing from the classpath because linkis-common is <scope>provided</scope> and impala-frontend/impala-minimal-hive-exec exclude all transitive deps.

Why are the changes needed?

Building and deploying the current master from a clean checkout fails end-to-end:

• mvn package -Papache fails at the impala module.
• Skipping impala still produces a tarball, but starting services fails with snakeyaml/class loading errors.
• After working around those, RPC POST /api/rest_j/v1/rpc/receiveAndReply returns 404 because Spring Boot 2.7's default path_pattern_parser is incompatible with springfox 3.0.0 — the engineconn yml was missing the override.
• After fixing the override, Eureka Client still throws NoClassDefFoundError: org.apache.commons.lang.exception.ExceptionUtils because commons-lang 2.x is no longer transitively available.

Each fix has been validated independently and the full build now completes (BUILD SUCCESS, 18:42 min).

How was this patch tested?

• mvn clean package -Papache -DskipTests -Dmaven.javadoc.skip=true — full reactor build now passes (was: failure at linkis-engineplugin-impala).
• Deployed the produced tarball via deploy-upgrade.sh and verified:
  • All 6 services (mg-eureka, mg-gateway, ps-publicservice, cg-linkismanager, cg-entrance, cg-engineconnmanager) start and register with Eureka.
  • Shell engine task (jobId 126376) succeeds with output matching the echo payload.
  • PerformanceInterceptor shows /rpc/receiveAndReply returning in 504 ms (no /error forward = no 404).
  • Eureka heartbeat /rpc/receive steady at 2–3 ms.

Related

• These were originally prototyped on fix/dependency-versions (an older base). This branch was rebased onto the current master so the changes apply cleanly to the latest application-*.yml layout that master already migrated to.
