             Summary: HIVE-20776 causes view access regression
                 Key: HIVE-21227
                 URL: https://issues.apache.org/jira/browse/HIVE-21227
             Project: Hive
          Issue Type: Bug
          Components: Hive
    Affects Versions: 4.0.0
            Reporter: Na Li
            Assignee: Na Li


HIVE-20776 introduces a change that causes regression for view access.

Before the change, a user with select access of a view can get all columns of a view with select access of a view that is derived from a partitioned table.

With the change, that user cannot access that view.

The reason is that
* When user accesses columns of a view, Hive needs to get the partitions of the table that the view is derived from. The user name is the user who issues the query to access the view.
*  The change in HIVE-20776 checks if user has access to a table before getting its partitions. When user only has access of a view, not the access of a table itself, this change denies the user access of the view.
