@Private @Unstable package org.apache.hadoop.yarn.server.nodemanager.amrmproxy
Package org.apache.hadoop.yarn.server.nodemanager.amrmproxy contains classes for handling federation amrm information.
  • Class
    Description
    AbstractRequestInterceptor
    Implements the RequestInterceptor interface and provides common functionality which can can be used and/or extended by other concrete interceptor classes.
    AMRMProxyApplicationContext
    Interface that can be used by the interceptor plugins to get the information about one application.
    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.
    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.
    TokenAndRegisterResponse
    This class contains information about the AMRM token and the RegisterApplicationMasterResponse.
