How to build H2O from scratch on a Mac

By following the steps below, you should be able to build and run H2O on your Mac.

Note: This should work on a reasonably modern OS X (10.6 and up), but was only tested on OS X 10.9

1. Install Xcode via the Apple store https://itunes.apple.com/us/app/xcode/id497799835?ls=1&mt=12

2. Download and install Java 1.7 from http://www.oracle.com/technetwork/java/javase/downloads/index.html

3. Download and install R from http://cran.r-project.org/bin/macosx/

4. Optional: Install sphinx (for documentation)

sudo easy_install sphinx
sudo easy_install sphinxcontrib-fulltoc

5. Optional: Download and install LaTex from http://www.tug.org/mactex/index.html

6. Get H2O from github git clone https://github.com/0xdata/h2o.git

7. Build H2O cd h2o && make

8. Start H2O (optional: add "-name mycluster" and issue the following command multiple times for a virtual cluster) java -jar target/h2o.jar

9. Open up the H2O UI by pointing your browser to http://localhost:54321
