>             Project: Spark
>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 3.0.1
>            Reporter: Chao Sun

> For the following example:
> {code}
> CREATE TABLE t ...;
> CREATE VIEW t1 AS SELECT * FROM t;
> REFRESH TABLE t
> {code}
> If t is cached, t1 will be invalidated. However if t is not cached as above, the REFRESH command won't invalidate view t1. This could lead to incorrect result if the view is used later.
