ISO Date UDFs: Conversion, Rounding and Date Math
-------------------------------------------------
Key: PIG-1310
URL: https://issues.apache.org/jira/browse/PIG-1310
Project: Pig
Issue Type: New Feature
Components: impl
Reporter: Russell Jurney
Fix For: 0.7.0
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 series.
