Uses of FederationRouterPolicy in org.apache.hadoop.yarn.server.federation.policies.manager

Methods in org.apache.hadoop.yarn.server.federation.policies.manager that return FederationRouterPolicy

Modifier and Type	Method	Description
FederationRouterPolicy	AbstractPolicyManager.getRouterPolicy(FederationPolicyInitializationContext federationPolicyContext, FederationRouterPolicy oldInstance)	This default implementation validates the FederationPolicyInitializationContext, then checks whether it needs to reinstantiate the class (null or mismatching type), and reinitialize the policy.
FederationRouterPolicy	FederationPolicyManager.getRouterPolicy(FederationPolicyInitializationContext policyContext, FederationRouterPolicy oldInstance)	If the current instance is compatible, this method returns the same instance of FederationRouterPolicy reinitialized with the current context, otherwise a new instance initialized with the current context is provided.

Modifier and Type	Class	Description
class	AbstractRouterPolicy	Base abstract class for FederationRouterPolicy implementations, that provides common validation for reinitialization.
class	HashBasedRouterPolicy	This FederationRouterPolicy pick a subcluster based on the hash of the job's queue name.
class	LoadBasedRouterPolicy	This implements a simple load-balancing policy.
class	LocalityRouterPolicy	This policy selects the subcluster depending on the node where the Client wants to run its application.
class	PriorityRouterPolicy	This implements a policy that interprets "weights" as a ordered list of preferences among sub-clusters.
class	RejectRouterPolicy	This FederationRouterPolicy simply rejects all incoming requests.
class	UniformRandomRouterPolicy	This simple policy picks at uniform random among any of the currently active subclusters.
class	WeightedRandomRouterPolicy	This policy implements a weighted random sample among currently active sub-clusters.
