> 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.
> The solution is when getting table partitions, do not filter on table at HMS
> client
