By default you would expect to find the logs files for master and workers in the relative `logs` directory from the root of the Spark installation on each of the respective nodes in the cluster.

I should also add I've recently seen this issue as well when using collect. I believe in my case it was related to heap space on the driver program not being able to handle the returned collection.
