  • The user can connect to a public HiveServer2 (via JDBC/ODBC) which is exposed to the outside of the Kubernetes cluster.
  • The user can connect to Apache HTTP Server which serves as a gateway to Superset, Ranger, Grafana, MR3-UI, and Spark UI.
  • Superset connects to an internal HiveServer2 which is not exposed to the outside of the Kubernetes cluster. Superset with an internal HiveServer2 is optional.
  • All HiveServer2 instances share a common MR3 DAGAppMaster and its ContainerWorkers. Autoscaling is enabled by default.
  • Multiple Spark drivers sharing a common MR3 DAGAppMaster and its ContainerWorkers can run inside the Kubernetes cluster. Autoscaling is enabled by default.
  • HiveServer2 and Spark drivers are automatically configured to share Metastore.
