Hey actually - instead of doing this, do you mind just "inlining" the
setting up of the PYTHONPATH into this file? `spark-config.sh` is intended to
configure Spark's standalone daemons, it's not meant to be used at all in mesos
mode. I realize the current approach fixes the problem, but it would be cleaner
to just have the mesos executor setup $PYTHONPATH directly.
```
export PYTHONPATH=$FWDIR/python:$PYTHONPATH
export PYTHONPATH=$FWDIR/python/lib/py4j-0.8.1-src.zip:$PYTHONPATH
```
