https://github.com/apache/spark/pull/17935
I was trying to run a test case from another database which _does_ support
unaliased subqueries in the `FROM` clause and hit a confusing parser error due
to this patch's behavior change. While I agree that we shouldn't necessarily
support this syntax, I think that the current error message that we're
returning isn't very good so I've file
https://issues.apache.org/jira/browse/SPARK-20916 to improve it.
