[jira] [Commented] (PIG-3664) Piggy Bank XPath UDF can't be called
[ https://issues.apache.org/jira/browse/PIG-3664?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13871380#comment-13871380 ]
Daniel Dai commented on PIG-3664:
---------------------------------
getArgToFuncMapping still better cuz we can capture schema mismatch in the frontend. I would prefer fix it rather than get rid of it.

> 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.
