Notes:
-  2.2.x-*-armimages support only the pre-installed components and the following optional components. The other 2.2 optional components and all initialization actions aren't supported:- Apache Hive WebHCat
- Docker
- Zeppelin
- Zookeeper (installed in high availability clusters ; optional component in other clusters)
 
-  The source code to image 2.2 libraries that are licensed under Reciprocal and Restricted licenses is available at the /usr/local/share/google/dataproc/third-party-sourcespath on Dataproc cluster VMs.
-  The following Hudi procedures are known to not work on a Hudi table backed by the Cloud Storage file system: -  run_clustering
-  run_compaction

-  The default resource calculator for YARN has been changed from DefaultResourceCalculator to DominantResourceCalculator , which uses the dominant-resource concept to determine resource allocation, such as Memory and CPU allocation. This change impacts Autoscaler , which scales based on the dominant resource usage of the cluster.
