### What changes were proposed in this pull request? This PR aims to downgrade the Apache Hadoop dependency to 3.3.4 in `Apache Spark 3.5` in order to prevent any regression from `Apache Spark 3.4.x`. In other words, although `Apache Spark 3.5.x` will lose many bug fixes of Apache Hadoop 3.3.5 and 3.3.6, it will be in the same situation with `Apache Spark 3.4.x`. - SPARK-44197 Upgrade Hadoop to 3.3.6 (#41744) - SPARK-42913 Upgrade Hadoop to 3.3.5 (#39124) - SPARK-43448 Remove dummy dependency `hadoop-openstack` (#41133) On top of reverting SPARK-44197 and SPARK-42913, this PR has additional dependency exclusion change due to the following. - SPARK-43880 Organize `hadoop-cloud` in standard maven project structure (#41380) ### Why are the changes needed? There is a community report on S3A committer performance regression. Although it's one liner fix, there is no available Hadoop release with that fix at this time. - HADOOP-18757: Bump corePoolSize of HadoopThreadPoolExecutor in s3a committer (apache/hadoop#5706) ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Pass the CIs. Closes #42345 from dongjoon-hyun/SPARK-44678. Authored-by: Dongjoon Hyun <[email protected]> Signed-off-by: Dongjoon Hyun <[email protected]>
