描述
I tried to leverage `org.apache.arrow.adapter.jdbc.JdbcToArrow.sqlToArrow` to query a Hive table but got the following error message on array columns.
`Configuration does not provide a mapping for array column 234`
The error message makes wondering whether it is possible to provided a customized configuration for array columns?

研究方向
從 org.apache.arrow.adapter.jdbc.JdbcToArrow.sqlToArrow 開始,檢查陣列欄位是如何進行映射的,然後閱讀關於設定 SQL 類型與 Arrow 類型之間映射的相關 issue。完成的標準是使用者可以為陣列欄位提供自訂映射,而不會出現回報的設定錯誤。
