> 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?
