> When I try to call XPath UDF to process a very simple XML with Pig 0.12 I get
> the problem:
> 2014-01-13 16:14:19,530 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR
> 1045:
> <line 3, column 25> Could not infer the matching function for
> org.apache.pig.piggybank.evaluation.xml.XPath as multiple or none of them
> fit. Please use an explicit cast. I guess the XPath UDF overrides the
> getArgToFuncMapping() in an incorrect way. A fixed is attached.
