Interface LongRunningYarnContainer

All Superinterfaces:

YarnContainer

All Known Implementing Classes:

AbstractBatchYarnContainer, AbstractIntegrationYarnContainer, AbstractYarnContainer, DefaultBatchYarnContainer, DefaultYarnContainer

public interface LongRunningYarnContainer
extends YarnContainer

Extension of YarnContainer indicating that container is intended to be a long running operation. Usually container will do its tasks and goes away by its own, but in some use cases it is appropriate to allow container to be kept up and running by hooking to its states.

Usual case is to ask from method isWaitCompleteState() if runner should wait complete state via listener which is registered using method addContainerStateListener(ContainerStateListener).
