Hi Kyuubi developers, Recently, I've been looking at the code of the Hive engine, one of my goals id to make it support multiple versions of Hive runtime, including - 3.1.3, which is the latest stable version of Apache Hive, already supported - 2.3.9, which is the latest stable version of Apache Hive 2.x, is adopted widely, including Apache Spark, Apache Flink - 2.1.1-cdh6.3.2, the latest free version of CDH, has lots of users
When I tried to run the Hive engine built against Hive 3.x with Hive 2.3.9/2.1.1-cdh6.3.2 runtime, I encountered some thrift class conflict issues which were hard to resolve, thus I propose to create a pre-shaded hive-service-rpc to tackles such issue. I have created two PRs[1][2] to demonstrate and verify my idea, it also introduces additional benefits, e.g. speed up the engine packaging by reducing relocation classes. Looking forward to the community feedback and PR reviews. Once the idea is accepted, and [1] gets merged, I will start the kyuubi-shaded release voting.
