> Currently, all the Gridmix input data files are located at <gridmix-io-dir>/input (<gridmix-io-dir> is expected as a CLI parameter). When compression emulation is enabled, Gridmix will check for compressed files (based on suffixes) in the input folder. Gridmix will bail out if there are no compressed input files. If the input folder consists of a mix of compressed and uncompressed input files, then Gridmix will only use compressed input files for all the jobs. Gridmix should smartly assign 
> 1. uncompressed input files for jobs the don't need input decompression 
> 2. compressed input files for jobs that need input decompression
