Package org.apache.hadoop.yarn.server.resourcemanager.rmcontainer

Interface RMContainer

All Superinterfaces:

java.lang.Comparable<RMContainer>, org.apache.hadoop.yarn.event.EventHandler<RMContainerEvent>

All Known Implementing Classes:

RMContainerImpl

public interface RMContainer
extends org.apache.hadoop.yarn.event.EventHandler<RMContainerEvent>, java.lang.Comparable<RMContainer>

Represents the ResourceManager's view of an application container. See RMContainerImpl for an implementation. Containers may be in one of several states, given in RMContainerState. An RMContainer instance may exist even if there is no actual running container, such as when resources are being reserved to fill space for a future container allocation.
