Dave Beech commented on CRUNCH-165:
-----------------------------------
Great work Josh, thanks! I was looking forward to trying this out but I hit
MAPREDUCE-1806 on our version of Hadoop... I'll give it another go when I have
something to read from HDFS rather than S3.
> Pipelines should automatically use CombineFileInputFormat where input
> consists of many small files

> Hive had a feature introduced in HIVE-74 whereby CombineFileInputFormat would
> be used if the input data consisted of many small files, making the resulting
> mapreduce jobs more efficient by giving individual mappers more data to
> process. This would be a nice feature for Crunch to have, too.
