[KYUUBI apache#6036] JDBC driver conditional sets fetchSize on openin…
…g session # 🔍 Description ## Issue References 🔗 I get reported by a user that using Kyuubi JDBC driver 1.8.0 to access Spark Thrift Server 2.4 (with Hive 1.2.1) with getting an error on opening the session even with `clientProtocol=7` ``` org.apache.hive.service.cli.HiveSQLException: java.lang.IllegalArgumentException: hive configuration hive.server2.thrift.resultset.default.fetch.size does not exists. at org.apache.hive.service.cli.session.HiveSessionImpl.configureSession(HiveSessionImpl.java:220) at org.apache.hive.service.cli.session.HiveSessionImpl.open(HiveSessionImpl.java:154) at org.apache.hive.service.cli.session.SessionManager.openSession(SessionManager.java:258) ... 13 more ``` ## Describe Your Solution 🔧 When `hive.conf.validation` is `true` (it also is the default value), an IllegalArgumentException will be thrown if the provided configurations start with `hive.` and can not be recognized by the server. One solution is to disable `hive.conf.validation` on the server side, but we can also address it by avoiding passing this configuration if we know that the server does not support it. HIVE-14901 (2.3.0, HIVE_CLI_SERVICE_PROTOCOL_V10) introduces `hive.server2.thrift.resultset.default.fetch.size`, so we can set this configuration only when protocol >= HIVE_CLI_SERVICE_PROTOCOL_V10 ## Types of changes 🔖 - [ ] Bugfix (non-breaking change which fixes an issue) - [x] New feature (non-breaking change which adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) ## Test Plan 🧪 Verified locally by connecting to HS2 2.1.1 and HS2 2.3.9 #### Behavior Without This Pull Request ⚰️ IllegalArgumentException throws when using `jdbc:hive2://localhost:10000/default;clientProtocol=8` to connect HS2 2.1.1 Everything is OK when using `jdbc:hive2://localhost:10000/default` to connect HS2 2.3.9 #### Behavior With This Pull Request 🎉 Everything is OK when using `jdbc:hive2://localhost:10000/default;clientProtocol=8` to connect HS2 2.1.1 Everything is OK when using `jdbc:hive2://localhost:10000/default` to connect HS2 2.3.9 --- # Checklist 📝 - [x] This patch was not authored or co-authored using [Generative Tooling](https://www.apache.org/legal/generative-tooling.html) **Be nice.
