Documentation says the MAX function can be used on chararray, but it can't
--------------------------------------------------------------------------
Key: PIG-2303
URL: https://issues.apache.org/jira/browse/PIG-2303
Project: Pig
Issue Type: Bug
Components: documentation
Reporter: Graham Lea
Priority: Trivial
Here: http://pig.apache.org/docs/r0.9.0/func.html#max
It says MIN/Max can be used on chararray, but the result of those functions is
always a double.
Had to search through the Pig Javadoc to find that I should use
StringMin/StringMax instead.
