Dmitriy V. Ryaboy commented on PIG-1303:
----------------------------------------
Right, I'm with you on what the problem is.
My suggestion is to look at the FuncSpec of the parent EvalFunc, and if it
includes parameters, assume an equivalent FuncSpec should be created for
initial, intermediate, and final classes. Essentially do the same thing we do
for regular EvalFuncs when they are DEFINEd to use parameterized constructors.
You would then have to make sure that initial, intermediate, and final classes
have the required constructors, but that's what you'd expect to have to do
anyway.

> Key: PIG-1303
> URL: https://issues.apache.org/jira/browse/PIG-1303
> 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
> Assignee: Dmitriy V. Ryaboy

> 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.
