- Hive version 1.2.2 → 2.3.9 in dependencies.gradle - Added hive-serde (split from hive-metastore in 2.3.9) - Added DataNucleus/Derby/javax.jdo test deps (consolidated in root build.gradle) - Added calcite-druid test dep (Hive 2.3.9 references DruidQuery at runtime) - Pentaho exclusion (not in Maven Central) - Hive CBO disabled via systemProperty (CalcitePlanner incompatible with Calcite 1.21.0.265) - Excluded problematic Hive 2.3.9 transitives from coral-common (log4j-core, javax.servlet from Jetty orbit, slf4j-log4j12) to prevent conflicts in downstream consumers like Trino - coral-service: use deps map instead of hardcoded Hive/Hadoop versions - StaticHiveFunctionRegistry: disabled TRANSLATE3, split substr/substring - MetastoreProvider: getProxy(conf) → getProxy(conf, true) (API change in 2.3.9) - Disabled 3 tests: testEnumUnionString, testTranslateFunction (x2)
- .java-version: 1.8 → 17 - Java 17 toolchain in root build.gradle - --add-opens JVM args for tests (Hive/Hadoop/Derby use reflection) - Spotless 5.9.0 → 6.25.0 (old version incompatible with Java 17) - Spring Boot 2.7.18 → 3.3.5 (2.x does not support Java 17) - javax.annotation-api dependency (removed from JDK in Java 11+) - Float precision test updates (Java 17 Double.toString improvement) - Disabled Spark testScalaVersionWithSparkSession (Java 17 SecurityException)
