[Gridmix] Input data compression emulation might not work as expected with data reuse
-------------------------------------------------------------------------------------

                 Key: MAPREDUCE-2616
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2616
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: contrib/gridmix
    Affects Versions: 0.23.0
            Reporter: Amar Kamat
            Assignee: Amar Kamat
             Fix For: 0.23.0


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 might end up using uncompressed files resulting into no emulation.
