@InterfaceAudience.Public

public abstract class ApplicationId
extends Object
implements Comparable<ApplicationId>

ApplicationId represents the globally unique identifier for an application.

The globally unique nature of the identifier is achieved by using the cluster timestamp i.e. start-time of the ResourceManager along with a monotonically increasing counter for the application.
