Bowen Li commented on FLINK-15858:
----------------------------------
I'm ok with the proposed solution.
However, that means users cannot use basic SQL like "describe <table>" in Hive,
as stated in example of
[https://ci.apache.org/projects/flink/flink-docs-master/dev/table/hive/hive_catalog.html#step-4-start-sql-client-and-create-a-kafka-table-with-flink-sql-ddl]
Another solution is to store precisions for such data types in properties and
keep the schema still in Hive table schema.
