Juhyun Seo created HIVE-28116: --------------------------------- 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? -- This message was sent by Atlassian Jira (v8.20.10#820010)
