Config (Cassandra Plugins 1.8.3 API)

java.lang.Object
- org.apache.cassandra.config.Config

```
public class Config
extends Object
```
TODO: remove once guava is removed from cdap-api This is a copy of the Configuration class in Cassandra, except it replaces usage of Sets.newConcurrentHashSet() with Collections.newSetFromMap(new ConcurrentHashMap()) to avoid guava version conflicts. A class that contains configuration properties for the cassandra node it runs within. Properties declared as volatile can be mutated via JMX.
