## On your client machine

### As the `root` user

1. Install DSE
2. In the cassandra.yml file, ensure the datacenter and cluster match your analytics datacenter
3. In the cassandra-env.sh file add this configuration line toward the bottom
   `JVM_OPTS="$JVM_OPTS -Dcassandra.join_ring=false"`
   This will make your DSE node a coordinator only, it will not own any data.  You can use this node to submit jobs to DSE locally without the need to know which is the master node.
3. start DSE
4. Install python
5. Install virtualenv

### As the `cassandra` user
```
> virtualenv .jupyter
> source .jupyter/bin/activate
> pip install ipython
> pip install jupyter
> PYSPARK_SUBMIT_ARGS="$PYSPARK_SUBMIT_ARGS pyspark-shell" IPYTHON_OPTS="notebook --ip='*' --no-browser" dse pyspark
```

## Notes
You can use something like `supervisord` to keep jupyter running in the background.

If you are getting a permission denied error when starting pyspark that look slike this: 
`OSError: [Errno 13] Permission denied: '/run/user/505/jupyter'`
It is because the XDG_RUNTIME_DIR is set to your logged in user, in that case just add the following environment variable before starting pyspark:
`JUPYTER_RUNTIME_DIR="$HOME/.jupyter/runtime`
