> Consider the query:
> {code}
> A = load 'a';
> B = order A by $0;
> C = join A by $0, B by $0;
> explain C;
> {code}
> works. But if replicated join is used instead
> {code}
> A = load 'a';
> B = order A by $0;
> C = join A by $0, B by $0 using "replicated";
> explain C;
> {code}
> this fails with ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2034: Error
