I've been trying to figure out how to increase the heap space for my spark
environment in 1.0.0, and all of the things I've found tell me I have export
something in Java Opts, which is deprecated in 1.0.0, or in increase the
spark.executor.memory, which is at 6G. I'm only trying to process about
400-500 mB of text, but I get this error whenever I try to collect:

Any idea how to fix heap space errors in 1.0.0?
