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 addresses runtime classpath issues introduced by the gcsio 3.0 upgrade. By explicitly including the necessary Hadoop utility dependencies for GCS, it ensures that the Iceberg integration can correctly identify and utilize the required file system implementations during test execution and runtime.

Highlights

• Dependency Resolution: Added bigdataoss_util_hadoop as a runtime dependency to resolve 'UnsupportedFileSystemException' errors related to GCS file system access.
• Iceberg Configuration: Updated the expansion service build configuration to include Iceberg dependencies unconditionally, removing the previous Java version-based conditional check.

Code Review

This pull request updates a trigger file, adds a Hadoop utility dependency to the Iceberg SQL extension, and removes a Java version guard for Iceberg dependencies in the expansion service. The reviewer identified that removing the Java 8 compatibility check for Iceberg dependencies will cause an UnsupportedClassVersionError in Java 8 environments, as Iceberg 1.7.0+ requires Java 11. It is recommended to restore the guard and include the new Hadoop dependency within it.
