public class StandaloneResourceManager
extends ResourceManager<ResourceID>

A standalone implementation of the resource manager. Used when the system is started in standalone mode (via scripts), rather than via a resource framework like YARN or Mesos.

This ResourceManager doesn't acquire new resources.

Method Detail

initialize

protected void initialize()
                   throws ResourceManagerException

Description copied from class: ResourceManager

Initializes the framework specific components.

Specified by:

initialize in class ResourceManager<ResourceID>

Throws:

ResourceManagerException - which occurs during initialization and causes the resource manager to fail.

internalDeregisterApplication

protected void internalDeregisterApplication(ApplicationStatus finalStatus,
                                             @Nullable
                                             String diagnostics)

Description copied from class: ResourceManager

The framework specific code to deregister the application. This should report the application's final status and shut down the resource manager cleanly.

This method also needs to make sure all pending containers that are not registered yet are returned.

Specified by:

internalDeregisterApplication in class ResourceManager<ResourceID>

Parameters:

finalStatus - The application status to report.

diagnostics - A diagnostics message or null.

startNewWorker

public Collection<ResourceProfile> startNewWorker(ResourceProfile resourceProfile)

Description copied from class: ResourceManager

Allocates a resource using the resource profile.

Specified by:

startNewWorker in class ResourceManager<ResourceID>

Parameters:

resourceProfile - The resource description

Returns:

Collection of ResourceProfile describing the launched slots

stopWorker

public boolean stopWorker(ResourceID resourceID)

Description copied from class: ResourceManager

Stops the given worker.

Specified by:

stopWorker in class ResourceManager<ResourceID>

Parameters:

resourceID - The worker.

Returns:

True if the worker was stopped, otherwise false

workerStarted

protected ResourceID workerStarted(ResourceID resourceID)

Description copied from class: ResourceManager

Callback when a worker was started.

Specified by:

workerStarted in class ResourceManager<ResourceID>

Parameters:

resourceID - The worker resource id

startServicesOnLeadership

protected void startServicesOnLeadership()

Overrides:

startServicesOnLeadership in class ResourceManager<ResourceID>
