For this release, the version to download is 2.35.4 https://repo1.maven.org/maven2/software/amazon/awssdk/bundle/2.35.4/)
Download the bundle-2.35.4.jar artifact and check its signature with the accompanying bundle-2.35.4.jar.asc file.
Copy the JAR to share/hadoop/common/lib/
(Newer AWS SDK versions should work, though regressions are almost inevitable)
