> The Hive side listing in FetchOperator.java is unnecessary, since Hadoop's
> FileInputFormat.java 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.
