### Search before asking - [x] I have searched in the issues and found no similar issues. ### What would you like to be improved? The community voted to discontinue Hadoop 2 support in the next Amoro release: https://lists.apache.org/thread/st8v4l80cwytmlj79cm7793xjyw8zf3q The repository still includes the `hadoop2` Maven profile, Hadoop 2 CI and distribution configurations, and installation instructions. The Flink optimizer image also installs a Hadoop 2 uber JAR independently of the Maven-selected Hadoop version. This issue tracks implementing the vote outcome separately from the Iceberg upgrade in #4377 and #4378. ### How should we improve? - Remove the `hadoop2` Maven profile and the dependency artifact selection used for Hadoop 2 builds. - Remove Hadoop 2 CI, binary distribution and Docker image variants, and dependency inventories. - Run Trino CI without the `hadoop2` profile. - Replace the Flink optimizer image's Hadoop 2 uber JAR with the Maven-selected Hadoop 3 client libraries. - Update build, installation and release documentation while retaining historical release download links. Verify that supported engine builds continue to work and that the Flink optimizer image loads Hadoop 3 and reads Parquet successfully. ### Are you willing to submit PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's Code of Conduct. -- This is an automated message from the Apache Git Service.
