Method Detail

init

public void init(org.apache.hadoop.conf.Configuration config,
                 RMContext context,
                 ResourceScheduler sched)

Specified by:

init in interface SchedulingEditPolicy

reinitialize

public void reinitialize(org.apache.hadoop.conf.Configuration config,
                         RMContext context,
                         ResourceScheduler sched)

Reinitializes queues(Called on scheduler.reinitialize)

Parameters:

config - Configuration

context - The resourceManager's context

sched - The scheduler

editSchedule

public void editSchedule()

Description copied from interface: SchedulingEditPolicy

This method is invoked at regular intervals. Internally the policy is allowed to track containers and affect the scheduler. The "actions" performed are passed back through an EventHandler.

Specified by:

editSchedule in interface SchedulingEditPolicy

getMonitoringInterval

public long getMonitoringInterval()

Specified by:

getMonitoringInterval in interface SchedulingEditPolicy

getPolicyName

public java.lang.String getPolicyName()

Specified by:

getPolicyName in interface SchedulingEditPolicy

getResourceCalculator

public org.apache.hadoop.yarn.util.resource.ResourceCalculator getResourceCalculator()

getRmContext

public RMContext getRmContext()

getRC

public org.apache.hadoop.yarn.util.resource.ResourceCalculator getRC()

getScheduler

public CapacityScheduler getScheduler()

getManagedParentQueues

public java.util.Set<java.lang.String> getManagedParentQueues()
