Gerrit Jansen van Vuuren commented on PIG-1117:
-----------------------------------------------
Work has started on uploading the hive jars to the official maven repos.
This will allow the build to not have to use the ant get command but do this
via ivy (much cleaner).
Once this is done I'll move the HiveColumnarLoader source to the main directory
and remove the hive-libs dir from the build.

> 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?
