Major Description
These methods are not used concurrently, they are part of the initialization code of NM that happens from one thread.
This is the list of the call hierarchies:
1. GpuResourcePlugin.initialize + ResourcePluginManager.initialize
GpuResourcePlugin.initialize(Context) (org.apache.hadoop.yarn.server.nodemanager.containermanager.resourceplugin.gpu) ResourcePluginManager.initialize(Context) (org.apache.hadoop.yarn.server.nodemanager.containermanager.resourceplugin) NodeManager.serviceInit(Configuration) (org.apache.hadoop.yarn.server.nodemanager)
2. GpuResourcePlugin.createResourceHandler:
GpuResourcePlugin.createResourceHandler(Context, CGroupsHandler, PrivilegedOperationExecutor) (org.apache.hadoop.yarn.server.nodemanager.containermanager.resourceplugin.gpu) ResourceHandlerModule.addHandlersFromConfiguredResourcePlugins(List, Configuration, Context) (org.apache.hadoop.yarn.server.nodemanager.containermanager.linux.resources) ResourceHandlerModule.initializeConfiguredResourceHandlerChain(Configuration, Context) (org.apache.hadoop.yarn.server.nodemanager.containermanager.linux.resources) ResourceHandlerModule.getConfiguredResourceHandlerChain(Configuration, Context) (org.apache.hadoop.yarn.server.nodemanager.containermanager.linux.resources) ContainerScheduler.serviceInit(Configuration) (org.apache.hadoop.yarn.server.nodemanager.containermanager.scheduler) LinuxContainerExecutor.init(Context) (org.apache.hadoop.yarn.server.nodemanager)
3. GpuResourcePlugin.getNodeResourceHandlerInstance:
