functools.partial as UserDefinedFunction

Hi all,

passing a functools.partial-function as a UserDefinedFunction to 
DataFrame.select raises an AttributeException, because functools.partial 
does not have the attribute __name__. Is there any alternative to 
relying on __name__ in pyspark/sql/functions.py:126 ?

Hi,

I've filed a JIRA (https://issues.apache.org/jira/browse/SPARK-6553) and 
suggested a fix (https://github.com/apache/spark/pull/5206).

It’s good to support functools.partial, could you file a JIRA for it?
