Johannes Rußek commented on PIG-1303:
-------------------------------------
I'm sorry, but is this really the problem with the DateExtractor UDF?
what i've seen during debugging is that it implements getArgToFuncMapping which
returns a funcspec without the constructor arguments. I've tried to look into
it but i didn't find an easy way to figure the initial constructor arguments
out when getArgToFuncMapping is being called.
also, DateExtractor isn't even algebraic. i'm not sure, but what's wrong with
keeping the constructor arguments from the first instantiation and apply them
to any further ones, may it be algebraic child classes or pig type-specific
implementations?

> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.6.0
> Environment: pig 0.6.0 on a fedora linux machine, jdk 1.6 u11
> Reporter: Johannes Rußek

> Attachments: TypeCheckingVisitor.java.diff

> I'm unable to set the format of the outgoing date string in the constructor
> as it's supposed to work.
> The only way i could change the format was to change the default in the java
> class and rebuild piggybank.
> Apparently this has something to do with the way pig instantiates
> DateExtractor, quoting a replier on the mailing list:
> David Vrensk said:
> I ran into the same problem a couple of weeks ago, and
> played around with the code inserting some print/log statements. It turns
> out that the arguments are only used in the initial constructor calls, when
> the pig process is starting, but once pig reaches the point where it would
> use the udf, it creates new DateExtractors without passing the arguments.
