Subject [jira] Commented: (PIG-1310) ISO Date UDFs: Conversion, Trucation and Date Math
Date Tue, 30 Mar 2010 19:54:27 GMT

    [ https://issues.apache.org/jira/browse/PIG-1310?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12851542#action_12851542

Russell Jurney commented on PIG-1310:

Cool - one thing though - Piggybank itself does not build in trunk.  It must not have built
since 0.6, since the load/store func changes went in.  Does something need to be done there?
 Should I submit a patch that removes all the broken UDFs to make ant build in piggybank work
on trunk?

To get piggybank to build, I had to remove:

!       contrib/piggybank/java/src/test/java/org/apache/pig/piggybank/test/storage/TestMultiStorage.java
!       contrib/piggybank/java/src/test/java/org/apache/pig/piggybank/test/storage/TestSequenceFileLoader.java
!       contrib/piggybank/java/src/test/java/org/apache/pig/piggybank/test/storage/TestRegExLoader.java
!       contrib/piggybank/java/src/test/java/org/apache/pig/piggybank/test/TestPigStorageSchema.java
!       contrib/piggybank/java/src/test/java/org/apache/pig/piggybank/test/evaluation/string/TestLookupInFiles.java
!       contrib/piggybank/java/src/test/java/org/apache/pig/piggybank/test/evaluation/TestEvalString.java

Is this just me, is this fixed on other branches?

>            Reporter: Russell Jurney

>             Fix For: 0.7.0

>   Original Estimate: 168h
>  Remaining Estimate: 168h
> I've written UDFs to handle loading unix times, datemonth values and ISO 8601 formatted
date strings, and working with them as ISO datetimes using jodatime.
> The working code is here: http://github.com/rjurney/oink/tree/master/src/java/oink/udf/isodate/
> It needs to be documented and tests added, and a couple UDFs are missing, but these work
if you REGISTER the jodatime jar in your script.  Hopefully I can get this stuff in piggybank
before someone else writes it this time :)  The rounding also may not be performant, but the
code works.
> Ultimately I'd also like to enable support for ISO 8601 durations.  Someone slap me if
this isn't done soon, it is not much work and this should help everyone working with time
