Class Configuration

  • All Implemented Interfaces:
    Serializable, Cloneable
    public class Configuration
extends Object
implements Serializable, Cloneable

    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.
