[jira] Updated: (PIG-1303) unable to set outgoing format for
org.apache.pig.piggybank.evaluation.util.apachelogparser.DateExtractor
[ https://issues.apache.org/jira/browse/PIG-1303?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Johannes Rußek updated PIG-1303:
--------------------------------
Attachment: TypeCheckingVisitor.java.diff
Hello everybody,
this fixes it for us.
Apparently due to the Typemagic the FuncSpec that is returned by our EvalFunc.getArgToFuncMapping() which doesn't contain the constructor arguments is used instead of the perfectly fine one in "func", which contains the constructor arguments.
We've just copied the arguments from func to matchingSpec to make it work.

> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.6.0

> 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.
