Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

Apache Cassandra Chef Cookbook

Build Status

This is a Chef cookbook for Apache Cassandra (DataStax Community Edition) as well as DataStax Enterprise.

It uses officially released packages and provides an Upstart service script. It has fairly complete support for adjustment of Cassandra configuration parameters using Chef node attributes.

It was originally created for CI and development environments and now supports cluster discovery using Chef search. Feel free to contribute what you find missing!

Supported Apache Cassandra Version

This cookbook currently provides

  • Cassandra 2.x via tarball
  • Cassandra 2.x (DataStax Community Edition) via packages.
  • DataStax Enterprise (DSE)

Supported OS Distributions

  • Ubuntu 11.04 through 14.04 via DataStax apt repo.
  • RHEL/CentOS via DataStax yum repo.
  • RHEL/CentOS/Amazon via tarball

Support JDK Versions

Cassandra 2.x requires JDK 7+, Oracle JDK is recommended.


The main recipe is cassandra-dse::default which together with the node[:cassandra][:install_method] attribute will be responsible for including the proper installation recipe and recipe cassandra-dse::config for configuring both datastax and tarball C* installation.

Two actual installation recipes are cassandra-dse::tarball and cassandra-dse::datastax. The former uses official tarball and thus can be used to provision any specific version.

The latter uses DataStax repository via packages. You can install different versions (ex. dsc20 for v2.0) available in the repository by altering :package_name attribute (dsc20 by default).

Recently we have moved all the configuration resources to a separate recipe cassandra-des::config, which means recipes cassandra-dse::tarball and cassandra-dse::datastax are only responsible for C* installation.

Users with cookbook version =<3.5.0 needs to update the run_list, in case of not using cassandra-dse::default recipe.

include_recipe cassandra-dse uses cassandra-dse::datastax as the default.

DataStax Enterprise

You can also install the DataStax Enterprise edition by adding node[:cassandra][:dse] attributes according to the datastax.rb. * node[:cassandra][:package_name]: Override default value to 'dse-full'. * node[:cassandra][:service_name]: Override default value to 'dse'.

Unencrypted Credentials: * node[:cassandra][:dse][:credentials][:username]: Your username from Datastax website. * node[:cassandra][:dse][:credentials][:password]: Your password from Datastax website.

Encrypted Credentials: * node[:cassandra][:dse][:credentials][:databag][:name]: Databag name, i.e. the value 'cassandra' will reference to /data_bags/cassandra. * node[:cassandra][:dse][:credentials][:databag][:item]: Databag item, i.e. the value 'main' will reference to /data_bags/cassandra/main.json. * node[:cassandra][:dse][:credentials][:databag][:entry]: The field name in the databag item, in which the credetials are written. i.e. the data_bag: { "id": "main", "entry": { "username": "%USERNAME%", "password": "%PASSWORD%" } }

There are also recipes for DataStax opscenter installation ( cassandra-dse::opscenter_agent_tarball, cassandra-dse::opscenter_agent_datastax, and cassandra-dse::opscenter_server ) along with attributes available for override (see below).

JNA Support (for C* Versions Prior to 2.1.0)

The node[:cassandra][:setup_jna] attribute will install the jna.jar in the /usr/share/java/jna.jar, and create a symbolic link to it on #{cassandra.lib\_dir}/jna.jar, according to the DataStax documentation.
