Subject [jira] Updated: (PIG-476) given a date that can match a SimpleDateFormat want to be able to extract arbitrary SimpleDateFormat data, like day or year
Date Tue, 14 Oct 2008 04:21:44 GMT

Earl Cahill updated PIG-476:
----------------------------

    Attachment: DateExtractor-PIG-476

I moved some javadoc down, and now on parsing failures, we just return, which results in an
empty string in out.  I also added a test case that tests making it past a failed parse.

"yyyy", "dd/MMM/yyyy:HH:mm:ss");
> to extract the year, or if your date is formatted as
