ok great - I also did some more debugging: (1) when the filename is specified inside the dml script, the file is indeed written to a directory ~ in HDFS, but (2) when passed from command line the ~ is of course resolved before it's even passed into SystemML.
So let's do the following: (1) use a small scenario of say 10K x 1K, (2) run it with absolute file name, and see what happens. If this does not work, I would suspect some permission issues next - maybe the bridge from python to the jvm hides some error output. If this is also not the case, please provide the -explain output and I have a closer look.
