SteNicholas opened a new pull request, #3747: URL: https://github.com/apache/celeborn/pull/3747
### What changes were proposed in this pull request? This PR removes Hadoop 2 client support from Celeborn. Specifically: - Remove the `hadoop-2` Maven profile from the root `pom.xml`, which was activated when `hadoop.version` matched `2.*` and pulled in `hadoop-client` with a long list of exclusions. - Remove the corresponding `hadoop-2` profiles (activated via the `hadoop-2-deps` property) from `common/pom.xml`, `master/pom.xml`, and `client-mr/mr/pom.xml`. - Update `README.md` to reflect that Celeborn supports Hadoop MapReduce 3 (instead of 2/3). ### Why are the changes needed? Hadoop 2 is an old release line that is no longer actively maintained. Dropping it reduces the build/dependency matrix and maintenance burden, allowing the project to focus on Hadoop 3. ### Does this PR resolve a correctness bug? - [ ] Yes ### Does this PR introduce _any_ user-facing change? - [x] Yes Celeborn no longer provides the `hadoop-2` build profile. Users building against Hadoop 2 must either upgrade to Hadoop 3 or stay on a previous Celeborn release. ### How was this patch tested? Existing CI. No new functionality is introduced; the change only removes build profiles and references. -- This is an automated message from the Apache Git Service.
