We could add a unit test for this specific case. But I am also looking for 
a way to treat these warnings as compile errors; which would be a lot better.

@hvanhovell there are two alternatives to match `tableProvider` rule:

 tableProvider
 tableOpts?
 (KW_AS selectStatementWithCTE)?

And

(LPAREN columnNameTypeList RPAREN)?
 (p=tableProvider?)
...

Because `(LPAREN columnNameTypeList RPAREN)` is optional, an input 
`KW_USING Identifier` can be matched with both paths. So the warning is emitted 
and path 1 is chosen and path 2 is disabled. Actually it doesn't affect the 
functionality we need.

@viirya thanks for working on this. Do you have an idea what functionality 
was disabled?

[SPARK-13277][SQL] ANTLR ignores other rule using the USING keyword

JIRA: https://issues.apache.org/jira/browse/SPARK-13277

There is an ANTLR warning during compilation:

alternatives: 2, 3

As a result, alternative(s) 3 were disabled for that input

This patch is to fix it.
