Brooklyn Blueprints for Cassandra 3.x Clusters in pure YAML

HOW TO USE:

Add cassandra-catalog.bom to your AMP catalog. A new item named "Cassandra cluster" will be available in the Create Application wizard. Select it then click "Next". You can specify a location and the configuration for it in the next page.

Available configuration parameters are:

• cassandra.archive.url (binary distribution URL)
• cassandra.cluster.nodes (# of nodes in the cluster)

You can also use the cassandra-cluster-template entity directly. For example, use this blueprint to deploy a cluster to Blue Box on CentOS:

name: Cassandra Cluster on Blue Box (LON)

location:
  ibm-bluebox-lon-vpn:
    osFamily: centos
    minRam: 1gb
    installDevUrandom: true
    loginUser: centos

services:
  - type: cassandra-cluster-template
    brooklyn.config:
      cassandra.archive.url: 'http://archive.apache.org/dist/cassandra/3.5/apache-cassandra-3.5-bin.tar.gz'
      cassandra.cluster.nodes: 2
      cassandra.cluster.name: 'my cluster'

It will start one node first and use its IP address as a seed for the other nodes.

Tested with Centos 7.2, Ubuntu 14.04, Ubuntu 15.10 on Blue Box and SoftLayer

TESTING:

Use the provided cassandra-cluster-test.yaml blueprint to perform a live test deployment.

The test case currently checks that

• the cluster nodes are all up within a specified timeout (10 minutes)
• the cluster_name is correctly configured on each node

KNOWN LIMITATIONS:

Only configures listen_address, seeds and cluster_name. Uses the defaults for everything else.
