Apache Hadoop 3.4.3

I have put together a release candidate (RC1) for Hadoop 3.4.3.

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-3.4.3-RC1/

The git tag is release-3.4.3-RC1, commit 9d50c688466

The maven artifacts are staged at
https://repository.apache.org/content/repositories/orgapachehadoop-1465

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-3.4.3-RC1/CHANGELOG.md

Release notes
https://dist.apache.org/repos/dist/dev/hadoop/hadoop-3.4.3-RC1/RELEASENOTES.md

Build note: the maven artifacts are off the aarch64 release, not the x86;
single builds on ec2 VMs through our cloud infra kept resulting in multiple
staging repos,
probably a side effect of our VPN setup.

AWS SDK
-------

Previous releases included a "lean" tar without the AWS SDK, and/or
encountered
problems with the size of the .tar artifacts.

Now all releases are built without the AWS SDK; it must be explicitly added
to
share/hadoop/common/lib/

To add aws support to hadoop, download from Maven Central the version of
the SDK
you wish to use:

https://central.sonatype.com/artifact/software.amazon.awssdk/bundle/versions

For this release, the version to download is 2.35.4
https://repo1.maven.org/maven2/software/amazon/awssdk/bundle/2.35.4/)

1. Download the bundle-2.35.4.jar artifact and check its signature with
   the accompanying bundle-2.35.4.jar.asc file.

2. Copy the JAR to share/hadoop/common/lib/

Newer AWS SDK versions _should_ work, though regressions are almost
inevitable.

Please try the release and vote. The vote will run for 5 days.

Here's my vote (with artifacts verified, including presence of hadoop-azure
and hadoop-aws in common/lib)

+1 (binding)
