Package org.apache.drill.yarn.appMaster

Class AMYarnFacadeImpl

java.lang.Object

org.apache.drill.yarn.appMaster.AMYarnFacadeImpl

All Implemented Interfaces:

AMYarnFacade

public class AMYarnFacadeImpl
extends Object
implements AMYarnFacade

Wrapper around the asynchronous versions of the YARN AM-RM and AM-NM interfaces. Allows strategy code to factor out the YARN-specific bits so that strategy code is simpler. Also allows replacing the actual YARN code with a mock for unit testing.
