[jira] [Commented] (HIVE-17832) Allow hive.metastore.disallow.incompatible.col.type.changes to be changed in metastore

    [ https://issues.apache.org/jira/browse/HIVE-17832?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16215807#comment-16215807 ] 

Sergey Shelukhin commented on HIVE-17832:
-----------------------------------------

I think this is by design that it cannot be changed. This is a correctness setting that should only be settable by administrator.

> hive.metastore.disallow.incompatible.col.type.changes when set to true, will disallow incompatible column type changes through alter table.  But, this parameter is not modifiable in HMS.  If HMS in not embedded into HS2, the value cannot be changed.
