    @SUDARSHAN My function above works with uncompressed data. In your example I think you are using gzip compression as you write files - and then after - trying to merge these together which fails. That isn't going to work, as you can't merge gzip files together. Gzip is not a Splittable Compression algorithm, so certainly not "mergable". You might test "snappy" or "bz2" compression - but gut feel is this will fail too on merge. Probably best best is to remove compression, merge raw files, then compress using a splittable codec.
