All Known Implementing Classes:

DefaultApplicationYarnClient

public interface ApplicationYarnClient
extends YarnClient

A ApplicationYarnClient is an extension of YarnClient introducing more direct semantics of an application. Core yarn and generally when something is executed on yarn, there are no hard dependencies of existing application files.

This interface adds these semantics by using an ApplicationDescriptor which an implementation can for example use to guard against various application problems like not overwriting existing application instance or trying to launch an application which doesn't exist.
