> s3.fs.buffer.dir defines the tmp folder where files will be written to before
> getting sent to S3. Right now this is limited to a single folder which
> causes to major issues.
> 1. You need a drive with enough space to store all the tmp files at once
> 2. You are limited to the IO speeds of a single drive
> This solution will resolve both and has been tested to increase the S3 write
> speed by 2.5x with 10 mappers on hs1.
