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
