> Some examples are given below.
> 1. When creating stage directory, FileUtils sets the directory permissions by
> running a set of chgrp and chmod commands. In systems like S3, this would not
> be relevant.
> 2. In some cases, fs.delete() is followed by fs.exists(). In this case, it
> might be redundant to check for exists() (lookup ops are expensive in systems
> like S3).
