Subject Re: scala: java.net.BindException?
Date Thu, 16 Oct 2014 22:26:49 GMT
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.
