## Testing Instructions

The fastest way to get up and running is to using Jupyter.

1. Install Jupyter if you haven't already (http://jupyter.org/install.html)

2. Download the release source, or checkout the release tag and
perform a 'make dev' which will build and start a docker based test
environment. You can also do a 'make dist' and Install Apache Toree
via `pip install dist/toree-pip/toree-0.5.0.tar.gz`
followed by `jupyter toree install`

- You need to set a valid Apache Spark 3.x home, which can be done via
`jupyter toree install --spark_home=/usr/local/spark`

- You may need to run with `sudo` for installation permission

- For all installation options, run `jupyter toree install --help-all`

4. Run a Jupyter notebook server via `jupyter notebook`

- If the notebook portion of Jupyter is not installed but Jupyter is,
you can install via `pip install notebook`

5. Create a notebook using "Apache Toree - Scala" from the dropdown under new
dev
6. Run Scala/Spark commands such as `sc.parallelize(1 to 100).sum()` in the
notebook

## Voting Instructions

The vote is open for at least 72 hours and passes if a majority of at least
3 +1 PMC votes are cast.
