Chao Sun created SPARK-33290:
--------------------------------
Summary: REFRESH TABLE should invalidate cache even though the
table itself may not be cached
Key: SPARK-33290
URL: https://issues.apache.org/jira/browse/SPARK-33290
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.
