> Assume you have a Hive table with one VARCHAR(N) column. The following now fails:
> CREATE TABLE ice_tbl STORED AS ICEBERG AS SELECT * FROM hive_tbl;
> Fails because varchar(N) is not a supported Iceberg column type. Note, simple varchar works because it's just a string under the hood.
> I think this behaviour is just fine, Hive also gives an error for the above, however, Hive has a switch called 'iceberg.mr.schema.auto.conversion' that when you turn on Hive would do a conversion into string for varchar(N) automatically. Also smallint and tinyint could be converted into int.
> Would be nice to have something similar in Impala.
