Thomas D'Silva commented on PHOENIX-4694:
-----------------------------------------
[~jamestaylor]
Instead of setting the parent table to null if the table is a view, should we
set the lock table name to current table name if the table is a view? We pass
the parent table to {{doDropTable}} which uses it to do some validation.
> Prevent locking of parent table when dropping view to reduce contention

> When there are many views with the same parent table, there's a lot of
> contention when adding new views and dropping existing views. The lock is
> only necessary when creating/dropping indexes, so should be removed in the
> case of views.
