Field	Description
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler.continuousSchedulingEnabled
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler.continuousSchedulingSleepMs
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler.nodeLocalityDelayMs
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler.rackLocalityDelayMs
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairSchedulerConfiguration.CONTINUOUS_SCHEDULING_ENABLED	Continuous scheduling is known to cause locking issue inside the scheduler in larger cluster, more than 100 nodes, use FairSchedulerConfiguration.ASSIGN_MULTIPLE to improve container allocation ramp up.
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairSchedulerConfiguration.CONTINUOUS_SCHEDULING_SLEEP_MS	Continuous scheduling is known to cause locking issue inside Only used when FairSchedulerConfiguration.CONTINUOUS_SCHEDULING_ENABLED is enabled
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairSchedulerConfiguration.DEFAULT_CONTINUOUS_SCHEDULING_ENABLED
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairSchedulerConfiguration.DEFAULT_CONTINUOUS_SCHEDULING_SLEEP_MS
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairSchedulerConfiguration.DEFAULT_LOCALITY_DELAY_NODE_MS
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairSchedulerConfiguration.DEFAULT_LOCALITY_DELAY_RACK_MS
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairSchedulerConfiguration.DEFAULT_RM_SCHEDULER_INCREMENT_ALLOCATION_MB
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairSchedulerConfiguration.DEFAULT_RM_SCHEDULER_INCREMENT_ALLOCATION_VCORES
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairSchedulerConfiguration.LOCALITY_DELAY_NODE_MS	Continuous scheduling is known to cause locking issue inside Only used when FairSchedulerConfiguration.CONTINUOUS_SCHEDULING_ENABLED is enabled
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairSchedulerConfiguration.LOCALITY_DELAY_RACK_MS	Continuous scheduling is known to cause locking issue inside Only used when FairSchedulerConfiguration.CONTINUOUS_SCHEDULING_ENABLED is enabled
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairSchedulerConfiguration.RM_SCHEDULER_INCREMENT_ALLOCATION_MB	The preferred way to configure the increment is by using the yarn.resource-types.{RESOURCE_NAME}.increment-allocation property, for memory: yarn.resource-types.memory-mb.increment-allocation
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairSchedulerConfiguration.RM_SCHEDULER_INCREMENT_ALLOCATION_VCORES	The preferred way to configure the increment is by using the yarn.resource-types.{RESOURCE_NAME}.increment-allocation property, for CPU: yarn.resource-types.vcores.increment-allocation

Deprecated Methods

Method	Description
org.apache.hadoop.yarn.server.resourcemanager.RMAppManager.submitApplication(ApplicationSubmissionContext, long, String)
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler.getContinuousSchedulingSleepMs()	linked to FairScheduler.isContinuousSchedulingEnabled() deprecation
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler.getNodeLocalityDelayMs()	linked to FairScheduler.isContinuousSchedulingEnabled() deprecation
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler.getRackLocalityDelayMs()	linked to FairScheduler.isContinuousSchedulingEnabled() deprecation
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler.isContinuousSchedulingEnabled()	Continuous scheduling should not be turned ON. It is deprecated because it can cause scheduler slowness due to locking issues. Schedulers should use assignmultiple as a replacement.
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairSchedulerConfiguration.getContinuousSchedulingSleepMs()	linked to FairSchedulerConfiguration.CONTINUOUS_SCHEDULING_ENABLED deprecation
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairSchedulerConfiguration.getLocalityDelayNodeMs()	linked to FairSchedulerConfiguration.CONTINUOUS_SCHEDULING_ENABLED deprecation
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairSchedulerConfiguration.getLocalityDelayRackMs()	linked to FairSchedulerConfiguration.CONTINUOUS_SCHEDULING_ENABLED deprecation
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairSchedulerConfiguration.isContinuousSchedulingEnabled()	use FairSchedulerConfiguration.ASSIGN_MULTIPLE to improve container allocation ramp up.
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FSOpDurations.addContinuousSchedulingRunDuration(long)
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.SchedulingPolicy.initialize(Resource)	Since it doesn't track cluster resource changes, replaced by SchedulingPolicy.initialize(FSContext).
