Configuration (AWS Java SDK for Amazon EMR 1.10.22 API)

java.lang.Object
- com.amazonaws.services.elasticmapreduce.model.Configuration

All Implemented Interfaces:

Serializable, Cloneable
```
public class Configuration
extends Object
implements Serializable, Cloneable
```
NOTE: Amazon EMR releases 4.x or later.

Specifies a hardware and software configuration of the EMR cluster. This includes configurations for applications and software bundled with Amazon EMR. The Configuration object is a JSON object which is defined by a classification and a set of properties. Configurations can be nested, so a configuration may have its own Configuration objects listed.
