> Project: Pig
> Issue Type: Bug
> Components: documentation
> Affects Versions: 0.3.0, 0.3.1
> Reporter: Bogdan Dorohonceanu
>
> ARITY is not documented in Pig Latin Manual:
> http://hadoop.apache.org/pig/docs/r0.3.0/piglatin.html
> It is only 1 time mentioned in FAQ:
> "Q: How do I prevent failure if some records don't have the needed number of
> columns?
> You can filter away those records by including the following in your Pig
> program:
> A = LOAD 'foo' USING PigStorage('\t');
> B = FILTER A BY ARITY(*) < 5;
> .....
> This code would drop all records that have fewer than five (5) columns."
