> 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
