Description

Script showing the problem:

 "a = load '/user/pig/tests/data/singlefile/studenttab10k' as (name, age, gpa:double); b = foreach a generate CONCAT(gpa, 'dummy'); dump b;"

Error shown:
2009-08-03 17:04:27,573 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1045: Could not infer the matching function for org.apache.pig.builtin.CONCAT as multiple or none of them fit. Please use an explicit cast.

The error goes away if gpa is casted to chararray.
