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 17:31:44 GMT

     [ https://issues.apache.org/jira/browse/PIG-476?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alan Gates updated PIG-476:
---------------------------

    Resolution: Fixed
        Status: Resolved  (was: Patch Available)

Patch checked in.  I took the liberty of adding a System.err.println at line 88 of DateExtractor.java
so that if the incomingDateFormat didn't parse an error message would be emitted.  Swallowing
exceptions is bad because users never know what went wrong.  Thanks Earl.

> Want to be able to do something like
> A = FOREACH raw GENERATE org.apache.pig.piggybank.evaluation.util.apachelogparser.DateExtractor(dayTime,
"yyyy", "dd/MMM/yyyy:HH:mm:ss");
> to extract the year, or if your date is formatted as
> dd/MMM/yyyy:HH:mm:ss Z
> you could do something like
> A = FOREACH raw GENERATE org.apache.pig.piggybank.evaluation.util.apachelogparser.DateExtractor(dayTime,
"MM-dd-yyyy");
> to grab out the day
