> I have SPARK_HOME set (because I installed spark via Homebrew). The toree installation initially failed:
> ```
> phase:~ me$ jupyter toree install
> [ToreeInstall] Installing toree kernel with interpreter Scala
> [ToreeInstall] Removing existing kernelspec in /usr/local/share/jupyter/kernels/toree_scala
> [ToreeInstall] Installed kernelspec toree_scala in /usr/local/share/jupyter/kernels/toree_scala
> Traceback (most recent call last):
>   File "/Users/me/Library/Python/2.7/bin/jupyter-toree", line 9, in <module>
>     load_entry_point('toree==0.1.0.dev5', 'console_scripts', 'jupyter-toree')()

>   File "/Users/me/Library/Python/2.7/lib/python/site-packages/toree/toreeapp.py", line 79, in create_kernel_json
>     python_lib_contents = listdir("{0}/python/lib".format(self.spark_home))
> OSError: [Errno 2] No such file or directory: '/usr/local/spark/python/lib'
> ```
> I got this working by running `jupyter toree install --spark_home=$SPARK_HOME`.
> It would be nice if SPARK_HOME were used automatically if it is set.
