Hi folks, Xiaoqiao He and I have put together a release candidate (RC2) for Hadoop 3.4.0.
What we would like is for anyone who can to verify the tarballs, especially anyone who can try the arm64 binaries as we want to include them too. The RC is available at: https://dist.apache.org/repos/dist/dev/hadoop/hadoop-3.4.0-RC2 The git tag is release-3.4.0-RC2, commit 88fbe62f27e The maven artifacts are staged at https://repository.apache.org/content/repositories/orgapachehadoop-1402 You can find my public key at: https://dist.apache.org/repos/dist/release/hadoop/common/KEYS Change log https://dist.apache.org/repos/dist/dev/hadoop/hadoop-3.4.0-RC2/CHANGELOG.md Release notes https://dist.apache.org/repos/dist/dev/hadoop/hadoop-3.4.0-RC2/RELEASENOTES.md This is off branch-3.4.0 and is the first big release since 3.3.6. Key changes include * S3A: Upgrade AWS SDK to V2 * HDFS DataNode Split one FsDatasetImpl lock to volume grain locks * YARN Federation improvements * YARN Capacity Scheduler improvements * HDFS RBF: Code Enhancements, New Features, and Bug Fixes * HDFS EC: Code Enhancements and Bug Fixes * Transitive CVE fixes Differences from RC0 & RC1 * We've improved Hadoop 3.4.0 Highlight big features and improvements. * Confirmed the JIRA status of Hadoop, HDFS, YARN, and MAPREDUCE modules. * Use validate-hadoop-client-artifacts[1] for packaging and verification. * Use hadoop-thirdparty-1.2.0 Note, because the arm64 binaries are built separately on a different platform and JVM, their jar files may not match those of the x86 release -and therefore the maven artifacts. I don't think this is an issue (the ASF actually releases source tarballs, the binaries are there for help only, though with the maven repo that's a bit blurred). The only way to be consistent would actually untar the x86.tar.gz, overwrite its binaries with the arm stuff, retar, sign and push out for the vote. Even automating that would be risky.
