Review comment:
The issue is in Hive's SerDe/Metastore. So, when you insert ANSI
intervals to a table where Hive SerDe is not involved (`provider` is parquet,
for instance), and we store schema in Spark's specific format to Hive external
catalog, I wonder why do you wonder that INSERT works well?
In that case, we use Hive MetaStore as a store for our schema only. HMS is
not aware of our types, right?
