Aniket Mokashi commented on PIG-2778:
-------------------------------------

[~rohini], you are right about this. I have noticed this earlier. Wouldn't this be fixed by
changing string representation OP_MATCH to https://github.com/apache/pig/blob/branch-0.12/src/org/apache/pig/Expression.java#l48?

> Currently the regex match operation does not get pushed down to LoadMetadata (and Expression
does not have an enum value for it); it would be quite useful to enable this for some optimizations.
