----------------------------
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.
