+1(binding) * checked hadoop-3.2.2-src.tar.gz * verified signature and checksums. * built on CentOS 8 and OpenJDK 8 by `mvn install -DskipTests -Pnative -Pdist`. * launched 3-node docker cluster with NN-HA and RM-HA enabled. * ran example MR jobs. * checked hadoop-3.2.2-site.tar.gz * verified signature and checksums. * skimmed the contents.
While I think it is not critical, the top page of site documentation seemed to be rolled back from the one for 3.2.1: https://hadoop.apache.org/docs/r3.2.1/ . # I could not find the index.md.vm for 3.2.1 in branch-3.2.1 and rel/release-3.2.1. The step #4 of "Branching" section in HowToRelease is relevant instruction. https://cwiki.apache.org/confluence/display/HADOOP2/HowToRelease | 4. Release branch (branch-X.Y.Z) updates: | a. Update hadoop-project/src/site/markdown/index.md.vm to reflect the right versions, new features and big improvements. The instruction might be a bit unclear and tend to be missed by release manager. # I missed this on 2.10.1 release.. Thanks, Masatake Iwasaki On 2020/12/10 2:00, Xiaoqiao He wrote:

Please try the release and vote. I have done a simple testing with my pseudo cluster. * Verify gpg sign and md5sum. * Setup pseudo cluster with HDFS and YARN. * Run simple FsShell - mkdir/put/get/rename/mv. * Submit example mr job and check the result - Pi/wordcount. * Check the web UI of NameNode/DataNode/Resourcemanager/NodeManager. My +1 to start.
