> Hello.
> I'm leaving an inquiry because I want to understand the
> "hive.metastore.disallow.incompatible.col.type.changes" setting in detail.
> When I read the
> [document|https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.metastore.disallow.incompatible.col.type.changes]
> it was found to be related to the possibility of converting the data type of
> the column and compatibility. However, if you use `ALTER TABLE
> iceberg.iceberg_db.iceberg_table DROP COLUMN 'name'`, the same error occurs.
> If you delete a column here, the data related to that column will be removed
> from the table, which I think is separate from the compatibility issue of
> data type, and I wonder what it has to do with this setting.
> can I check the code related to this?
