> From the documentation I understand that it should be possible to  filter a relation based on the equality of tuples. http://wiki.apache.org/pig/PigTypesFunctionalSpec , http://hadoop.apache.org/pig/docs/r0.5.0/piglatin_reference.html#deref:
>  However with this data file
> -- indext.txt:
> (1,one) (1,ONE)
> (2,two) (22, twentytwo)
> (3,three)       (3,three)
> I run this pig script:
> A = LOAD 'indext.txt' AS (t1:(a:int, b:chararray), t2:(a:int, b:chararray)); B = FILTER A BY t1==t2; DUMP B;
> Expecting the output:
> ((3,three),(3,three))
> However there is an error:
