Dmitriy V. Ryaboy commented on PIG-1303:
----------------------------------------
Attached a patch for both regular UDFs and Algebraics. It's essentially what
Johannes posted, I just added a test (but see the rest of this comment), and
applied the same logic to Algebraic EvalFunc construction.
The test only really tests algebraic instantiation; I haven't been successful
in reproducing the normal instantiation problem in test mode (which is probably
why it's gone undetected so far). There's a test for it in my patch, but it's a
bad one -- the test actually passes even without the patch to the
TypeCheckingVisitor.
Johannes, could you try applying this patch and let us know if it fixes your
DateExtractor problem?
hc, this patch should unblock you for PIG-1386

> Affects Versions: 0.6.0
> Environment: pig 0.6.0 on a fedora linux machine, jdk 1.6 u11
> Reporter: Johannes Rußek

> 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.
