Hi,
I have sritten a javscript UDF and as mentioned in pig guide
<http://pig.apache.org/docs/r0.9.2/udf.html#udf-java> .I have declared the
outputschema in my js file
parseString.outputSchema = "dataMap:chararray";
whereas same datatype is availble in my pig script too.
A = LOAD '$input_file' AS(
number3:int,number4:float,dataMap:chararray);
Still I am getting below error
2015-07-07 01:46:59,466 [main] ERROR org.apache.pig.tools.grunt.GruntParser
