> 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.
