thanks marcelo. i only instantiated sparkcontext once, at the beginning,
in this code. the exception was thrown right at the beginning.
i also tried to run other programs, which worked fine previously, but now
also got the same error.
it looks like it put global block on creating sparkcontext that prevents
any program to create a sparkcontext.

This error is not fatal, since Spark will retry on a different port..
but this might be a problem, for different reasons, if somehow your
code is trying to instantiate multiple SparkContexts.
I assume nn.SimpleNeuralNetwork is part of your application, and
since it seems to be instantiating a new SparkContext and also is
being called from an iteration, that looks sort of fishy.
