[yanghua]

The demo refers to hudi's official site: https://hudi.apache.org/docs/docker_demo It involved:

• Kafka
• Hudi
• Spark
• Hive
• Trino
• Kyuubi (plus)

For consideration of scalability, each component has an ansible Role. And connect them via Ansible Playbook.

Each Role should follow ansible galaxy specification.
