>             Project: Hive
>          Issue Type: Bug
>          Components: Parser
>    Affects Versions: 4.0.0
>            Reporter: Jesus Camacho Rodriguez
>            Assignee: Laszlo Bodor
>            Priority: Major

>
>
> These are the warnings at compilation time:
> {code}
> warning(200): IdentifiersParser.g:424:5:
> Decision can match input such as "KW_UNKNOWN" using multiple alternatives: 1, 10
> As a result, alternative(s) 10 were disabled for that input
> {code}
> This means that multiple parser rules can match certain query text, possibly leading
to unexpected errors at parsing time.
