Olga Natkovich commented on PIG-1046:
-------------------------------------
The changes look good. One thing that was missed for both group and join is
that the string after using is one of the strings that we recognize and give an
error otherwise.
> join algorithm specification is within double quotes

> This fails -
> j = join l1 by $0, l2 by $0 using 'skewed';
> This works -
> j = join l1 by $0, l2 by $0 using "skewed";
> String constants are single-quoted in pig-latin. If the algorithm
> specification is supposed to be a string, specifying it within single quotes
> should be supported.
> Alternatively, we should be using identifiers here, since these are
> pre-defined in pig users will not be specifying arbitrary values that might
> not be valid identifier.
