Examples of org.rhq.cassandra.Deployer

org.rhq.cassandra.Deployer
Deployment consists of a few steps.
1. Unzip Cassandra to disk.
2. Update configuration files like casssandra.yaml. This involves performing variable substitution.
3. Update file permissions to make scripts in the bin directory executable.
The values used in the variable substitution are supplied by an instance of {@link DeploymentOptions}. @author John Sanda
