[jira] [Assigned] (SPARK-16678) Disallow Creating a View when the
same-name Table Exists
[ https://issues.apache.org/jira/browse/SPARK-16678?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

> --------------------------------------------------------
>
> Key: SPARK-16678
> URL: https://issues.apache.org/jira/browse/SPARK-16678
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Xiao Li
>
> When we create 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
> {noformat}
