Description

Consider the query:

A = load 'a';
B = order A by $0;
C = join A by $0, B by $0;
explain C;

works. But if replicated join is used instead

A = load 'a';
B = order A by $0;
C = join A by $0, B by $0 using "replicated";
explain C;

this fails with ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2034: Error compiling operator POFRJoin
