> PIG-4674 added schema inferring for TOMAP.
> {code}
> FOREACH A GENERATE (val == 'x' ? TOMAP('key', floatfield1) : (val == 'y' ? 
> GenerateFloatMap('key', floatfield2) : NULL)) as floatmap:map[float],
> {code}
> The following line fails with
> {code}
> Two inputs of BinCond must have compatible schemas. left hand side: 
> #675:map(#676:float) right hand side: #801:map
>       at 
> org.apache.pig.newplan.logical.visitor.TypeCheckingExpVisitor.visit(TypeCheckingExpVisitor.java:616)
>       ... 45 more
> {code}
> GenerateFloatMap is a UDF that returns new HashMap<String, Float>(), but does 
> not have outputSchema() defined. It worked earlier because TOMAP also did not 
> have outputSchema() defined.
