Summary: I'm curious about the
"hive.metastore.disallow.incompatible.col.type.changes" settings.
Key: HIVE-28116
URL: https://issues.apache.org/jira/browse/HIVE-28116
Project: Hive
Issue Type: Task
Reporter: Juhyun Seo
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?
