>
> This method, if run on compressed input, results in corrupt output since it
> just does a byte-by-byte concatenation disregarding compression codecs. It
> should automatically detect compression codecs from input files and handle
> them intelligently.
> Additionally, there should be an option to create a compressed output file so
> that the output can be efficiently stored and sent out to customers (over the
> network outside the cluster).
