Overview

A Puppet module to install and manage Cassandra, DataStax Agent & OpsCenter

Setup

What Cassandra affects

What the Cassandra class affects

Installs the Cassandra package (default dsc22).
Configures settings in ${config_path}/cassandra.yaml.
Optionally ensures that the Cassandra service is enabled and running.
On Ubuntu systems, optionally replace /etc/init.d/cassandra with a workaround for CASSANDRA-9822.

What the cassandra::datastax_agent class affects

Optionally installs the DataStax agent.
Optionally sets JAVA_HOME in /etc/default/datastax-agent.

What the cassandra::datastax_agent class affects

Optionally configures a Yum repository to install the Cassandra packages from (on Red Hat).
Optionally configures an Apt repository to install the Cassandra packages from (on Ubuntu).

What the cassandra::firewall_ports class affects

Optionally configures the firewall for the Cassandra related network ports.

What the cassandra::java class affects

Optionally installs a JRE/JDK package (e.g. java-1.7.0-openjdk) and the Java Native Access (JNA).

What the cassandra::opscenter class affects

Installs the OpsCenter package.
Manages the content of the configuration file (/etc/opscenter/opscenterd.conf).
Manages the opscenterd service.

What the cassandra::opscenter::cluster_name type affects

An optional type that allows DataStax OpsCenter to connect to a remote key space for metrics storage. These files will be created in /etc/opscenter/clusters. The module also creates this directory if required. This functionality is only valid in DataStax Enterprise.

What the cassandra::opscenter::pycrypto class affects

On the Red Hat family it installs the pycrypto library and it's pre-requisites (the python-devel and python-pip packages).
Optionally installs the Extra Packages for Enterprise Linux (EPEL) repository.
As a workaround for PUP-3829 a symbolic link is created from /usr/bin/pip to /usr/bin/pip-python. Hopefully this can be removed in the not too distant future.

What the cassandra::optutils class affects

Optionally installs the Cassandra support tools (e.g. cassandra22-tools).

Beginning with Cassandra

A basic example is as follows:

  class { 'cassandra':
    cluster_name    => 'MyCassandraCluster',
    endpoint_snitch => 'GossipingPropertyFileSnitch',
    listen_address  => "${::ipaddress}",
    seeds           => '110.82.155.0,110.82.156.3'
  }

Upgrading

Changes in 1.8.0

A somewhat embarrassing correction to the spelling of the cassandra::fail_on_non_suppoted_os to cassandra::fail_on_non_supported_os.

Issues when Upgrading to 1.4.0

Unfortunately both releases 1.3.7 and 1.4.0 have subsequently been found to call a refresh service even when no changes had been made to the underlying configuration. In release 1.8.0 (somewhat belatedly) the service_refresh flag has been introduced to mitigate against similar problems.

Issues When Upgrading to 1.3.7

Please see the notes for 1.4.0.

Changes in 1.0.0

cassandra::cassandra_package_ensure has been renamed to cassandra::package_ensure.
cassandra::cassandra_package_name has been renamed to cassandra::package_name.

Changes in 0.4.0

There is now a cassandra::datastax_agent class, therefore:

cassandra::datastax_agent_package_ensure has now been replaced with cassandra::datastax_agent::package_ensure.
cassandra::datastax_agent_service_enable has now been replaced with cassandra::datastax_agent::service_enable.
cassandra::datastax_agent_service_ensure has now been replaced with cassandra::datastax_agent::service_ensure.
cassandra::datastax_agent_package_name has now been replaced with cassandra::datastax_agent::package_name.
cassandra::datastax_agent_service_name has now been replaced with cassandra::datastax_agent::service_name.

Likewise now there is a new class for handling the installation of Java:

cassandra::java_package_ensure has now been replaced with cassandra::java::ensure.
cassandra::java_package_name has now been replaced with cassandra::java::package_name.

Also there is now a class for installing the optional utilities:

cassandra::cassandra_opt_package_ensure has now been replaced with cassandra::optutils:ensure.
cassandra::cassandra_opt_package_name has now been replaced with cassandra::optutils:package_name.

Changes in 0.3.0

cassandra_opt_package_ensure changed from 'present' to undef.
The manage_service option has been replaced with service_enable and service_ensure.

Usage

Create a Cluster in a Single Data Center

In the DataStax documentation Initializing a multiple node cluster (single data center) http://docs.datastax.com/en/cassandra/2.2/cassandra/initialize/initSingleDS.html there is a basic example of a six node cluster with two seeds to be created in a single data center spanning two racks. The nodes in the cluster are:

Node Name	IP Address
node0 (seed 1)	110.82.155.0
node1	110.82.155.1
node2	110.82.155.2
node3 (seed 2)	110.82.156.3
node4	110.82.156.4
node5	110.82.156.5

Each node is configured to use the GossipingPropertyFileSnitch and 256 virtual nodes (vnodes). The name of the cluster is MyCassandraCluster. Also, while building the initial cluster, we are setting the auto_bootstrap to false.

In this initial example, we are going to expand the example by:

Ensuring that the software is installed via the DataStax Community repository by including cassandra::datastax_repo. This needs to be executed before the Cassandra package is installed.
That a suitable Java Runtime environment (JRE) is installed with Java Native Access (JNA) by including cassandra::java. This need to be executed before the Cassandra service is started.

node /^node\d+$/ {
  class { 'cassandra::datastax_repo':
    before => Class['cassandra']
  }

  class { 'cassandra::java':
    before => Class['cassandra']
  }

  class { 'cassandra':
    cluster_name    => 'MyCassandraCluster',
    endpoint_snitch => 'GossipingPropertyFileSnitch',
    listen_address  => "${::ipaddress}",
    num_tokens      => 256,
    seeds           => '110.82.155.0,110.82.156.3',
    auto_bootstrap  => false
  }
}

The default value for the num_tokens is already 256, but it is included in the example for clarity. Do not forget to either set auto_bootstrap to true or not set the parameter at all after initializing the cluster.

Create a Cluster in Multiple Data Centers

To continue with the examples provided by DataStax, we look at the example for a cluster across multiple data centers http://docs.datastax.com/en/cassandra/2.2/cassandra/initialize/initMultipleDS.html.

Node Name	IP Address	Data Center	Rack
node0 (seed 1)	10.168.66.41	DC1	RAC1
node1	10.176.43.66	DC1	RAC1
node2	10.168.247.41	DC1	RAC1
node3 (seed 2)	10.176.170.59	DC2	RAC1
node4	10.169.61.170	DC2	RAC1
node5	10.169.30.138	DC2	RAC1

For the sake of simplicity, we will confine this example to the nodes:

node /^node[012]$/ {
  class { 'cassandra':
    cluster_name    => 'MyCassandraCluster',
    endpoint_snitch => 'GossipingPropertyFileSnitch',
    listen_address  => "${::ipaddress}",
    num_tokens      => 256,
    seeds           => '10.168.66.41,10.176.170.59',
    dc              => 'DC1',
    auto_bootstrap  => false
  }
}

node /^node[345]$/ {
  class { 'cassandra':
    cluster_name    => 'MyCassandraCluster',
    endpoint_snitch => 'GossipingPropertyFileSnitch',
    listen_address  => "${::ipaddress}",
    num_tokens      => 256,
    seeds           => '10.168.66.41,10.176.170.59',
    dc              => 'DC2',
    auto_bootstrap  => false
  }
}

We don't need to specify the rack name (with the rack parameter) as RAC1 is the default value. Again, do not forget to either set auto_bootstrap to true or not set the parameter at all after initializing the cluster.

OpsCenter

To continue with the original example within a single data center, say we have an instance of OpsCenter running on a node called opscenter which has an IP address of 110.82.157.6. We add the cassandra::datastax_agent to the cassandra node to connect to OpsCenter:

node /^node\d+$/ {
  class { 'cassandra::datastax_repo':
    before => Class['cassandra']
  } ->
  class { 'cassandra::java':
    before => Class['cassandra']
  } ->
  class { 'cassandra':
    cluster_name    => 'MyCassandraCluster',
    endpoint_snitch => 'GossipingPropertyFileSnitch',
    listen_address  => "${::ipaddress}",
    num_tokens      => 256,
    seeds           => '110.82.155.0,110.82.156.3',
    before          => Class['cassandra::datastax_agent']
  } ->
  class { 'cassandra::datastax_agent':
    stomp_interface => '110.82.157.6'
  }
}

node /opscenter/ {
  include '::cassandra::datastax_repo' ->
  include '::cassandra' ->
  include '::cassandra::opscenter'
}

We have also added the cassandra::opscenter class for the opscenter node.

DataStax Enterprise

After configuring the relevant repository, the following snippet works on CentOS 7 to install DSE Cassandra 4.7.0:

class { 'cassandra::datastax_repo':
  descr   => 'DataStax Repo for DataStax Enterprise',
  pkg_url => 'https://username:password@rpm.datastax.com/enterprise',
  before  => Class['cassandra'],
}

class { 'cassandra':
  cluster_name   => 'MyCassandraCluster',
  config_path    => '/etc/dse/cassandra',
  package_ensure => '4.7.0-1',
  package_name   => 'dse-full',
  service_name   => 'dse',
}

Also with DSE, one can specify a remote keyspace for storing the metrics for a cluster. An example is:

cassandra::opscenter::cluster_name { 'Cluster1':
  cassandra_seed_hosts       => 'host1,host2',
  storage_cassandra_username => 'opsusr',
  storage_cassandra_password => 'opscenter',
  storage_cassandra_api_port => 9160,
  storage_cassandra_cql_port => 9042,
  storage_cassandra_keyspace => 'OpsCenter_Cluster1'
}

Parameters

`service_name`

The name of the service to be notified if a change is made to the configuration file. Typically this would by opscenterd.

`path`

The path to the configuration file. Typically this would by /etc/opscenter/opscenterd.conf.

`section`

The section in the configuration file to be added to (e.g. webserver).

`setting`

The setting within the section of the configuration file to changed (e.g. port).

`value`

The setting value to be changed to (e.g. 8888).

Limitations

Tested on the Red Hat family versions 6 and 7, Ubuntu 12.04 and 14.04, Debian 7 Puppet (CE) 3.7.5 and DSC 2.

From release 1.6.0 of this module, regular updates of the Cassandra 1.X template will cease and testing against this template will cease. Testing against the template for versions of Cassandra >= 2.X will continue.
