[jira] [Commented] (HIVE-26157) Change Iceberg storage handler authz URI to metadata location

["Sungwoo Park (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-26157?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17654074#comment-17654074 ] 

Sungwoo Park commented on HIVE-26157:
-------------------------------------

Calling IcebergTableUtil.getTable() in the new code throws the same NullPointerException as reported in HIVE-25964, e.g., when creating Iceberg tables from existing ORC tables using CTAS with hive.security.authorization.enabled set to true. Is this patch an improvement that can be reverted at the cost of efficiency?

> In HIVE-25964, the authz URI has been changed to "iceberg://db.table".
> It is possible to set the metadata pointers of table A to point to table B, and therefore you could read table B's data via querying table A.
> {code:sql}
> alter table A set tblproperties ('metadata_location'='/path/to/B/snapshot.json', 'previous_metadata_location'='/path/to/B/prev_snapshot.json');  {code}
