Removing hive-exec which brings joda-time and other dependencies shaded.
for tests, shaded is used, but ensuring order of dependencies - full hive-exec fat jar is strictly needed for embedded cluster setups due to many dependencies.

Summary of Changes

Hello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refines the dependency management for the HCatalog module, specifically addressing how hive-exec and its transitive dependencies are handled during compilation and testing. The changes aim to resolve dependency conflicts, particularly with joda-time, by differentiating between compile-time and test-time requirements. This ensures a cleaner build environment while providing the necessary full dependencies for robust test execution, especially for embedded Hive setups.

Highlights

  • Dependency Management for Hive-exec: The hive-exec dependency for compilation has been updated to use the core classifier, specifically org.apache.hive:hive-exec:core, to avoid bringing in shaded dependencies like joda-time during compilation.
  • Test Dependency Configuration: The full, shaded hive-exec JAR is now explicitly used for tests, ensuring that embedded cluster setups have all necessary dependencies. Several test dependencies (hive-hcatalog-core:tests, hive-common, hive-cli, hive-hcatalog-core) have been configured to exclude joda-time and hive-exec to prevent dependency conflicts.
  • New Test Dependencies: Added new test dependencies including hive-standalone-metastore-common, hive-standalone-metastore-server, calcite-core, and datasketches-hive to support comprehensive testing scenarios.
  • Joda-Time Dependency: joda-time has been explicitly added as both a provided and testImplementation dependency to manage its presence on the classpath.
  • JVM Arguments for Tests: JVM arguments --add-opens=java.base/java.net=ALL-UNNAMED have been added to all test tasks to address potential issues with Java module system restrictions during testing.
  • Documentation Update: The HCatalog documentation has been updated to reflect the use of the core classifier for the hive-exec dependency in Maven examples.

Code Review

This pull request updates the build.gradle file for the HCatalog IO module to use the hive-exec:core classifier for compilation and manages joda-time and other dependencies more explicitly, especially for testing. It also adds necessary JVM arguments for Java module system compatibility to test tasks. The documentation for HCatalog IO has been updated to reflect the hive-exec:core classifier usage. The changes improve dependency management and ensure compatibility with newer Java versions.

The joda_time library is already declared as an implementation dependency on line 48. Adding it again as a provided dependency on line 56 might be redundant unless there's a specific reason related to dependency resolution order or classpath management for the provided scope that is not immediately apparent. If the implementation declaration already covers the need for joda_time during compilation, this line can be removed to avoid redundancy.

Similar to the provided declaration, joda_time is already an implementation dependency on line 48. If the implementation dependency is sufficient for test compilation and runtime, this testImplementation declaration might be redundant. Please confirm if this explicit testImplementation is necessary, perhaps due to specific test classpath requirements or to override a transitive dependency.

The jvmArgs for --add-opens is already applied globally to all Test tasks via the tasks.withType(Test).configureEach block starting on line 130. This specific declaration on line 126 for hadoopVersion${kv.key}Test tasks becomes redundant and can be removed.
