> Hi.
> 1. If you use ; in pig script it breaks parsing
> 2. It's impossible to pass ; as a value for parameter. Pig starts grunt and doesn't start script.
> Here is example:
> {code}
> A = LOAD 'myFile';
> B = FOREACH A GENERATE ( host == ';' ? 1 : 0); --line #5
> {code}
> Here is stacktrace:
> {code}
