I merged all the latest stuff from master. But still this PR diff shows this change. This is weird. I checked the pyspark file from your branch https://github.com/MLnick/spark/blob/streaming-eg-algebird/pyspark and the mesos spark branch https://github.com/mesos/spark/blob/streaming/pyspark . Both seem to have the commit. Not sure why this is still showing up. Can you update your branch with all the changes of mesos/spark/streaming branch, just to be sure.
