             Summary: Last MR job in Hive should be able to write to a different scratch directory
                 Key: HIVE-15121
                 URL: https://issues.apache.org/jira/browse/HIVE-15121
             Project: Hive
          Issue Type: Sub-task
          Components: Hive
            Reporter: Sahil Takiar


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.
