This is inconsistent with Hive and causes problems when using [ROLE](https://cwiki.apache.org/confluence/display/Hive/SQL+Standard+Based+Hive+Authorization) in Hive. We had better to fix this.\r\n\r\n**BEFORE**\r\n```scala\r\nscala> sql(\"create table t(a int)\").show\r\nscala> sql(\"desc formatted t\").show(false)\r\n...\r\n|Owner:
