    Description

      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 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?
