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!
This cookbook targets Chef 12 and later versions.

cookbook 'cassandra-dse', '~> 4.5.0'cookbook 'cassandra-dse', github: 'michaelklishin/cassandra-chef-cookbook'This cookbook currently provides
- Cassandra via tarballs
- Cassandra (DataStax Community Edition) via apt and yum packages
- DataStax Enterprise (DSE) via packages
- Ubuntu 14.04 through 18.04 via DataStax apt repo.
- RHEL/CentOS via DataStax yum repo.
- RHEL/CentOS/Amazon via tarball
Cassandra 2.x requires JDK 7+, later versions require Oracle JDK 8+.
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
=<3.5.0needs to update therun_list, in case of not usingcassandra-dse::defaultrecipe.
include_recipe cassandra-dse uses cassandra-dse::datastax as the default.
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).
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.
Please note that the maintainers try to keep the list below up-to-date but it fairly often misses some recently added attributes. Please refer to the attributes files if an attribute you are looking for isn't listed.

Attributes used to define JBOD functionality
