Github user willb commented on the pull request: https://github.com/apache/spark/pull/189#issuecomment-38330588 @mateiz, I was pretty confused about this but it looks like the python accumulator tests are what is failing. I'm not super-familiar with pyspark yet but am trying to figure out where things are going wrong. (If you have any advice for where I should start looking, I'd appreciate it!)
