[jira] [Commented] (PIG-1314) Add DateTime Support to Pig

["Zhijie Shen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIG-1314?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13288203#comment-13288203 ] 

Zhijie Shen commented on PIG-1314:
----------------------------------

One more issue needs to be clarified:

In the AugmentBaseDataVisitor class, there're two functions: Object GetSmallerValue(Object v) and Object GetLargerValue(Object v). where if v is a numeric value, v is added or reduced by one while if v is a byte array, it is added or reduced by one byte. Then, how do we do if v is a datetime? I vote for returning null, and am looking forward to the community's opinions.

By the way, how about if v is a boolean, which seems not to be handled?

> 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
