Cassandra Install Using HowHow

Using thrx-framework-dropwizard:

<dependency>
	<groupId>org.thrx.service</groupId>
	<artifactId>thrx-framework-bom</artifactId>
	<version>${thrx.framework.version}</version>
	<type>pom</type>
	<scope>import</scope>
</dependency>
<dependency>
	<groupId>org.thrx.service</groupId>
	<artifactId>thrx-framework-cassandra</artifactId>
</dependency>

In your Configuration class, just add a CassandraClusterFactory member for configuration of the cluster connection:

class MyConfiguration extends Configuration {

    @NotNull
    @Valid
    private CassandraClusterFactory cassandra = new CassandraClusterFactory();

    @JsonProperty("cassandra")
    public CassandraClusterFactory getCassandraClusterFactory() {
        return cassandra;
    }

    @JsonProperty("cassandra")
    public void setCassandraClusterFactory(CassandraClusterFactory factory) {
        this.cassandra = factory;
    }
}

Finally, in your Application class, build an instance of the client:

class MyApplication extends Application<MyConfiguration> {

    @Override
    public void run(MyConfiguration configuration, Environment environment) {
        Cluster client = configuration
                .getCassandraClusterFactory()
                .build(environment);
    }
}

Cluster instances will be configured as defined by the CassandraClusterFactory and will automatically be managed as part of the application lifecycle.
