> Hive should be able to configure all intermediate MR jobs to write to HDFS,
> but the final MR job to write to S3.
> This will be useful for implementing parallel renames on S3. The idea is that
> for a mutli-job query, all intermediate MR jobs write to HDFS, and then the
> final job writes to S3. Writing to HDFS should be faster than writing to S3,
> so it makes more sense to write intermediate data to HDFS.
