Installs Apache hadoop and sets up a basic distributed cluster per the quick start documentation.
Tested on Ubuntu 8.10, though should work on most Linux distributions,
hadoop[:mirror_url]- Get a mirror from http://www.apache.org/dyn/closer.cgi/hadoop/core/.
hadoop[:version]- Specify the version of hadoop to install.
hadoop[:uid]- Default userid of the hadoop user.
hadoop[:gid]- Default group for the hadoop user.
hadoop[:java_home]- You will probably want to change this to match where Java is installed on your platform.
You may wish to add more attributes for tuning the configuration file templates.
This cookbook performs the tasks described in the Hadoop Quick Start to get the software installed. You should copy this to a site-cookbook and modify the templates to meet your requirements.
Once the recipe is run, the distributed filesystem can be formated using the script /usr/bin/hadoop.
sudo -u hadoop /usr/bin/hadoop namenode -format
You may need to set up SSH keys for hadoop management commands.
Note that this is not the 'default' config per se, so using the
start-all.sh script won't start the processes because the config files
live elsewhere. For running various hadoop processes as services, we
suggest runit. A sample 'run' script is provided. The
in the run script must exist for each process. These could be wrapped
in a define.
