org.apache.pig.newplan.logical.visitor.UnionOnSchemaSetter
A visitor that modifies the logical plan (if necessary) for union-onschema functionality. It runs logical plan validator so that the correct schema of its inputs is available. It inserts foreach statements in its input if the input operator schema does not match the schema created by merging all input schemas. Migrated from the old UnionOnSchemaSetter class.

        new ColumnAliasConversionVisitor( lp ).visit();
        new SchemaAliasVisitor( lp ).visit();


        CompilationMessageCollector collector = new CompilationMessageCollector() ;
        new TypeCheckingRelVisitor( lp, collector).visit();
        new UnionOnSchemaSetter( lp ).visit();
        new CastLineageSetter(lp, collector).visit(); 


        return lp;
       
    }
