Package org.apache.hadoop.yarn.server.nodemanager.amrmproxy contains classes for handling federation amrm information.

Interface Summary

Interface	Description
AMRMProxyApplicationContext	Interface that can be used by the interceptor plugins to get the information about one application.
RequestInterceptor	Defines the contract to be implemented by the request interceptor classes, that can be used to intercept and inspect messages sent from the application master to the resource manager.

Class Summary

Class	Description
AbstractRequestInterceptor	Implements the RequestInterceptor interface and provides common functionality which can can be used and/or extended by other concrete interceptor classes.
AMRMProxyApplicationContextImpl	Encapsulates the information about one application that is needed by the request interceptors.
AMRMProxyMetrics
AMRMProxyService	AMRMProxyService is a service that runs on each node manager that can be used to intercept and inspect messages from application master to the cluster resource manager.
AMRMProxyService.RequestInterceptorChainWrapper	Private structure for encapsulating RequestInterceptor and ApplicationAttemptId instances.
AMRMProxyTokenSecretManager	This secret manager instance is used by the AMRMProxyService to generate and manage tokens.
DefaultRequestInterceptor	Extends the AbstractRequestInterceptor class and provides an implementation that simply forwards the AM requests to the cluster resource manager.
FederationInterceptor	Extends the AbstractRequestInterceptor and provides an implementation for federation of YARN RM and scaling an application across multiple YARN sub-clusters.
TokenAndRegisterResponse	This class contains information about the AMRM token and the RegisterApplicationMasterResponse.
