Graham Lea commented on PIG-2303:
---------------------------------
Note: The error I was getting on entering the line using MIN + MAX into Grunt
was:
{code}
ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1022: Type mismatch merging
schema prefix. Field Schema: double. Other Field Schema: fieldName: chararray
{code}
(Just adding this to help people searching for this error message to find a
solution.)
> Documentation says the MAX function can be used on chararray, but it can't

> Here: http://pig.apache.org/docs/r0.9.0/func.html#max
