Sergio Peña commented on HIVE-15121:
------------------------------------
OK, I see what you're saying. The partial mask is beneficial on some cases
though, like doing a {{dfs -ls s3a://table}} in the .q test to verify final
files were written on S3. But for the EXPLAIN I understand the problem.
I'll do the quick fix.
> Last MR job in Hive should be able to write to a different scratch directory

> 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.
