# Apache Zeppelin on Vagrant Virtual Machine

<div id="toc"></div>

## Overview

Apache Zeppelin distribution includes a script directory

 `scripts/vagrant/zeppelin-dev`

This script creates a virtual machine that launches a repeatable, known set of core dependencies required for developing Zeppelin. It can also be used to run an existing Zeppelin build if you don't plan to build from source.
For PySpark users, this script includes several helpful [Python Libraries](#python-extras).
For SparkR users, this script includes several helpful [R Libraries](#r-extras).

### Prerequisites

This script requires three applications, [Ansible](http://docs.ansible.com/ansible/intro_installation.html#latest-releases-via-pip "Ansible"), [Vagrant](http://www.vagrantup.com "Vagrant") and [Virtual Box](https://www.virtualbox.org/ "Virtual Box").  All of these applications are freely available as Open Source projects and extremely easy to set up on most operating systems.

## Create a Zeppelin Ready VM

If you are running Windows and don't yet have python installed, [install Python 2.7.x](https://www.python.org/downloads/release/python-2710/) first.

1. Download and Install Vagrant:  [Vagrant Downloads](http://www.vagrantup.com/downloads.html)
2. Install Ansible:  [Ansible Python pip install](http://docs.ansible.com/ansible/intro_installation.html#latest-releases-via-pip)

    ```
    sudo easy_install pip
    sudo pip install ansible
    ansible --version
    ```
    After then, please check whether it reports **ansible version 1.9.2 or higher**.

3. Install Virtual Box: [Virtual Box Downloads](https://www.virtualbox.org/ "Virtual Box")
4. Type `vagrant up`  from within the `/scripts/vagrant/zeppelin-dev` directory

Thats it ! You can now run `vagrant ssh` and this will place you into the guest machines terminal prompt.

If you don't wish to build Zeppelin from scratch, run the z-manager installer script while running in the guest VM:

```
curl -fsSL https://raw.githubusercontent.com/NFLabs/z-manager/master/zeppelin-installer.sh | bash
```


## Building Zeppelin

You can now 

```
git clone git://git.apache.org/zeppelin.git
```

into a directory on your host machine, or directly in your virtual machine.

Cloning Zeppelin into the `/scripts/vagrant/zeppelin-dev` directory from the host, will allow the directory to be shared between your host and the guest machine.

Cloning the project again may seem counter intuitive, since this script likely originated from the project repository.  Consider copying just the vagrant/zeppelin-dev script from the Zeppelin project as a stand alone directory, then once again clone the specific branch you wish to build.

Synced folders enable Vagrant to sync a folder on the host machine to the guest machine, allowing you to continue working on your project's files on your host machine, but use the resources in the guest machine to compile or run your project. _[(1) Synced Folder Description from Vagrant Up](https://docs.vagrantup.com/v2/synced-folders/index.html)_

By default, Vagrant will share your project directory (the directory with the Vagrantfile) to `/vagrant`.  Which means you should be able to build within the guest machine after you
`cd /vagrant/zeppelin`


## What's in this VM?

Running the following commands in the guest machine should display these expected versions:

`node --version` should report *v0.12.7*
`mvn --version` should report *Apache Maven 3.3.9* and *Java version: 1.7.0_85*

The virtual machine consists of:

 - Ubuntu Server 14.04 LTS
 - Node.js 0.12.7
 - npm 2.11.3
 - ruby 1.9.3 + rake, make and bundler (only required if building jekyll documentation)
 - Maven 3.3.9
 - Git
 - Unzip
 - libfontconfig to avoid phatomJs missing dependency issues
 - openjdk-7-jdk
 - Python addons: pip, matplotlib, scipy, numpy, pandas
 - [R](https://www.r-project.org/) and R Packages required to run the R Interpreter and the related R tutorial notebook, including:  Knitr, devtools, repr, rCharts, ggplot2, googleVis, mplot, htmltools, base64enc, data.table

## How to build & run Zeppelin

This assumes you've already cloned the project either on the host machine in the zeppelin-dev directory (to be shared with the guest machine) or cloned directly into a directory while running inside the guest machine.  The following build steps will also include Python and R support via PySpark and SparkR:

```
cd /zeppelin
mvn clean package -Pspark-1.6 -Ppyspark -Phadoop-2.4 -Psparkr -DskipTests
./bin/zeppelin-daemon.sh start
```

On your host machine browse to `http://localhost:8080/`

If you [turned off port forwarding](#tweaking-the-virtual-machine) in the `Vagrantfile` browse to `http://192.168.51.52:8080`


## Tweaking the Virtual Machine

If you plan to run this virtual machine along side other Vagrant images, you may wish to bind the virtual machine to a specific IP address, and not use port fowarding from your local host.

Comment out the `forward_port` line, and uncomment the `private_network` line in Vagrantfile.  The subnet that works best for your local network will vary so adjust `192.168.*.*` accordingly.

```
#config.vm.network "forwarded_port", guest: 8080, host: 8080
config.vm.network "private_network", ip: "192.168.51.52"
```

`vagrant halt` followed by `vagrant up` will restart the guest machine bound to the IP address of `192.168.51.52`.
This approach usually is typically required if running other virtual machines that discover each other directly by IP address, such as Spark Masters and Slaves as well as Cassandra Nodes, Elasticsearch Nodes, and other Spark data sources.  You may wish to launch nodes in virtual machines with IP addresses in a subnet that works for your local network, such as: 192.168.51.53, 192.168.51.54, 192.168.51.53, etc..

## Extras
### Python Extras

With Zeppelin running, **Numpy**, **SciPy**, **Pandas** and **Matplotlib** will be available.  Create a pyspark notebook, and try the below code.

```python
%pyspark

import numpy
import scipy
import pandas
import matplotlib

print "numpy " + numpy.__version__
print "scipy " + scipy.__version__
print "pandas " + pandas.__version__
print "matplotlib " + matplotlib.__version__
```

To Test plotting using Matplotlib into a rendered `%html` SVG image, try

```python
%pyspark

import matplotlib
matplotlib.use('Agg')   # turn off interactive charting so this works for server side SVG rendering
import matplotlib.pyplot as plt
import numpy as np
import StringIO

# clear out any previous plots on this note
plt.clf()

def show(p):
    img = StringIO.StringIO()
    p.savefig(img, format='svg')
    img.seek(0)
    print "%html <div style='width:600px'>" + img.buf + "</div>"

# Example data
people = ('Tom', 'Dick', 'Harry', 'Slim', 'Jim')
y_pos = np.arange(len(people))
performance = 3 + 10 * np.random.rand(len(people))
error = np.random.rand(len(people))

plt.barh(y_pos, performance, xerr=error, align='center', alpha=0.4)
plt.yticks(y_pos, people)
plt.xlabel('Performance')
plt.title('How fast do you want to go today?')

show(plt)
```

### R Extras

With zeppelin running, an R Tutorial notebook will be available.  The R packages required to run the examples and graphs in this tutorial notebook were installed by this virtual machine.
The installed R Packages include: Knitr, devtools, repr, rCharts, ggplot2, googleVis, mplot, htmltools, base64enc, data.table
