Hi Shengkai. Thanks for driving the proposal of HiveServer2 Endpoint support. For the "GatewayService API Change", I don't think the motivation for supporting HiveServer2 endpoint need to change the GatewayService API, in other words, integrating the Hive ecosystem should not require changing the service interface. If you confirm to change GatewayService interface, IMO, the proposal could be discussed in FLIP-91 because the public interfaces are defined in FLIP-91.
In addtion, how to support different Hive versions and how to guarantee compatibility is not mentioned in the design. What's the behavior of the compatibility? Finally, for the public interfaces, could you please fully provide its definition including input parameters and the corresponding return value schema?
