Sorry about the @Author tag it was generated by eclipse automatically. I'll 
take that out and resubmit the patch.

I'll change the patch to make 2 releases;

One for 0.6 version.

And one for the new trunk version that contains the new method signatures for

> I've coded a LoadFunc implementation that can read from Hive Columnar RC 
> tables, this is needed for a project that I'm working on because all our data 
> is stored using the Hive thrift serialized Columnar RC format. I have looked 
> at the piggy bank but did not find any implementation that could do this. 
> We've been running it on our cluster for the last week and have worked out 
> most bugs.
> There are still some improvements to be done but I would need  like setting 
> the amount of mappers based on date partitioning. Its been optimized so as to 
> read only specific columns and can churn through a data set almost 8 times 
> faster with this improvement because not all column data is read.
> I would like to contribute the class to the piggybank can you guide me in 
> what I need to do?
> I've used hive specific classes to implement this, is it possible to add this 
> to the piggy bank build ivy for automatic download of the dependencies?
