public abstract class ApplicationSubmissionContext
extends Object

ApplicationSubmissionContext represents all of the information needed by the ResourceManager to launch the ApplicationMaster for an application.

It includes details such as:

• ApplicationId of the application.
• Application user.
• Application name.
• Priority of the application.
• ContainerLaunchContext of the container in which the ApplicationMaster is executed.
• maxAppAttempts. The maximum number of application attempts. It should be no larger than the global number of max attempts in the YARN configuration.
• attemptFailuresValidityInterval. The default value is -1. when attemptFailuresValidityInterval in milliseconds is set to > 0, the failure number will no take failures which happen out of the validityInterval into failure count. If failure count reaches to maxAppAttempts, the application will be failed.
• Optional, application-specific LogAggregationContext

Set the flag which indicates whether to keep containers across application attempts.

For managed AM, if the flag is true, running containers will not be killed when application attempt fails and these containers will be retrieved by the new application attempt on registration via ApplicationMasterProtocol.registerApplicationMaster(RegisterApplicationMasterRequest).

For unmanaged AM, if the flag is true, RM allows re-register and returns the running containers in the same attempt back to the UAM for HA.

Parameters:

keepContainers - the flag which indicates whether to keep containers across application attempts.

getNodeLabelExpression

@InterfaceAudience.Public
 @InterfaceStability.Evolving
public abstract String getNodeLabelExpression()

Get node-label-expression for this app. If this is set, all containers of this application without setting node-label-expression in ResurceRequest will get allocated resources on only those nodes that satisfy this node-label-expression. If different node-label-expression of this app and ResourceRequest are set at the same time, the one set in ResourceRequest will be used when allocating container
