> "hard to find error messages" what do you mean by that?
Mh, for example that the output of the failed python script was logged to
the ".out" file, and not immediately shown to the command line.
> what did you run the job with (data size, dop) ? did it happen multiple
times?
500 kb input data, dop=1, I only tried once.
Regarding the HDFS/local detection: I actually don't know a solution right
now. With Hadoop's FileSystem class, its easy, but we can not use that here.
