We use on-prem installation of 23.2.2-202307280452300417-9276e770, Enterprise Edition. Recently we tried to connect to Dremio via flight-sql-jdbc-driver-10.0.0.jar from [Dremio JDBC Drivers](https://www.dremio.com/drivers/jdbc/), using iceberg-spark-runtime-3.4\_2.12-1.4.3. In generally it works (for primitive types including timestamps), but we get an exception if we try to access ARRAY columns. The error: org.apache.spark.SparkSQLException: [UNRECOGNIZED\_SQL\_TYPE] Unrecognized SQL type - name: ARRAY, id: ARRAY. Anyone has any idea how this problem could be fixed ? ---

Hi @Alexarl I don’t believe that connector was written by Dremio. However, I see in the code of that connector that the corresponding for array in Arrow is list: [spark-flight-connector/README.md at 46ce7b6559705d0828f7e5b863495908563718f4 · qwshen/spark-flight-connector · GitHub](https://github.com/qwshen/spark-flight-connector/blob/46ce7b6559705d0828f7e5b863495908563718f4/README.md?plain=1#L267) Hopefully that helps, otherwise I suggest you get in touch with qwshen. Thanks, Bogdan
