[jira] [Updated] (PIG-1314) Add DateTime Support to Pig
[ https://issues.apache.org/jira/browse/PIG-1314?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Zhijie Shen updated PIG-1314:
-----------------------------
Attachment: PIG-1314-3.patch
Here's the newest patch of this issue, which contains the following changes since the last one:
1. Including the timezone when serializing datetime objects.
2. Implementing the additional UDFs that we have discussed.
3. Updating my previous modifications to solve some conflicts with the PIG-2632 patch.
4. Adding "timezone" configuration for Pig.
Util now, the patch can basically make the primitive datetime type work.
However, I've not do the thorough test yet. Therefore, my next step (in the second half of GSOC) will focus on coding the test cases, fixing bugs, etc.

> Hadoop/Pig are primarily used to parse log data, and most logs have a timestamp component. Therefore Pig should support dates as a primitive.
> Can someone familiar with adding types to pig comment on how hard this is? We're looking at doing this, rather than use UDFs. Is this a patch that would be accepted?
> This is a candidate project for Google summer of code 2012. More information about the program can be found at https://cwiki.apache.org/confluence/display/PIG/GSoc2012
