> When we create OR alter a view, we check whether the view already exists. In the current implementation, if a table with the same name exists, we treat it as a view. However, this is not the right behavior. We should follow what Hive does. For example,
> {noformat}
> hive> CREATE TABLE tab1 (id int);
> OK
> Time taken: 0.196 seconds
> hive> CREATE OR REPLACE VIEW tab1 AS SELECT * FROM t1;
> FAILED: SemanticException [Error 10218]: Existing table is not a view
>  The following is an existing table, not a view: default.tab1
> hive> ALTER VIEW tab1 AS SELECT * FROM t1;
> FAILED: SemanticException [Error 10218]: Existing table is not a view
>  The following is an existing table, not a view: default.tab1
> hive> CREATE VIEW IF NOT EXISTS tab1 AS SELECT * FROM t1;
> OK
> Time taken: 0.678 seconds
> {noformat}
