Description

When running a CTAS query using a hive table that has a tinyint, smallint, varchar or char column it fails with an "Unsupported Hive type" error message. This can be worked around if the 'iceberg.mr.schema.auto.conversion' property is set to true on session level. We should communicate this possibility when raising the exception.
