massive datasets distributed over fleets of machines from heterogeneous data sources. The Kyuubi Server lane of the below swimlane divides our prospective users into end users and administrators. On the complexity of business logic from the administrators. Therefore, they can upgrade components on the server side with zero maintenance downtime, optimize workloads with a clear view of what end users are doing using one copy of data, with one SQL interface. A Unified Gateway The Server module plays the role of a unified gateway. The server enables simplified, secure access to any cluster resource through an entry
