- Chef 12.3.0+
- CentOS 7.0+
- Ubuntu 14.04+
Recipes
-
install.rb
- Installs the Apache Hadoop Binaries -
nn.rb
- Configures and starts the NameNode -
dn.rb
- Configures and starts the DataNode -
rm.rb
- Configures and starts the ResourceManager -
nm.rb
- Configures and starts the NodeManager -
jhs.rb

Karamel usage
This cookbook is karamelized (www.karamel.io). You can launch a Hadoop Cluster using the following yml file. It will create 3 VMs, where one is the master running NameNode, ResourceManager, and Job history server. The two other VMs are workers and will run the DataNode and NodeManager.
