Subject [jira] Commented: (PIG-1303) unable to set outgoing format for org.apache.pig.piggybank.evaluation.util.apachelogparser.DateExtractor
Date Fri, 23 Apr 2010 06:16:52 GMT

    [ https://issues.apache.org/jira/browse/PIG-1303?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12860142#action_12860142

Dmitriy V. Ryaboy commented on PIG-1303:
----------------------------------------

hc,
I haven't gone through the code, but I think we should just try to do the same thing for initial,
intermediate, and final functions, in terms of instantiation, as is already being done for
the regular EvalFunc, and construct a better FuncSpec. I doubt we need the handleChildConstructorParams
function.

> 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.
