Describe the usage question you have. Please include as many useful details as possible.

I have an iceberg table with column type "TIMESTAMP_WITH_TIMEZONE"

When I run my flight_sql jdbc client to query this table, I get below error in my flight sql client code.

Exception in thread "Thread-0" java.lang.RuntimeException: java.sql.SQLException: Error while executing SQL "SELECT * FROM datawarehouse.school_data_raw.schools limit 100": Unknown error: java.lang.UnsupportedOperationException: Unmapped JDBC type: 2014

Query I am running is *SELECT FROM datawarehouse.school_data_raw.schools limit 100**

Table structure is :

_CREATE TABLE datawarehouse.school_data_raw.schools ( school_id varchar, school_name varchar, ingested_at timestamp(6) with time zone ) WITH ( format = 'PARQUET', format_version = 1, location = 's3a://data-warehouse/raw/schooldata/schools' )

Component(s)

Would it be possible to get a reproducible script?

Potentially related apache/arrow-java#171. Are you the owner of the AFS server? If not, what AFS service are you trying to query?
