> The Hive side listing in is unnecessary, since Hadoop's
will list the files during split computation anyway to determine their size. One way to remove
this is to catch the InvalidInputFormat exception thrown by FileInputFormat#getSplits() on
the Hive side instead of doing the file listing beforehand.
> For S3 select queries on partitioned tables, this results in a 2x speedup.
