Syntax

public sealed class AutoscalingPolicyBasicAlgorithmYarnConfig

Fields

GracefulDecommissionTimeout

Timeout for YARN graceful decommissioning of Node Managers. Specifies the duration to wait for jobs to complete before forcefully removing workers (and potentially interrupting jobs). Only applicable to downscaling operations. Bounds: [0s, 1d].

Declaration

public readonly string GracefulDecommissionTimeout

Field Value

Type	Description
System.String

ScaleDownFactor

Fraction of average pending memory in the last cooldown period for which to remove workers. A scale-down factor of 1 will result in scaling down so that there is no available memory remaining after the update (more aggressive scaling). A scale-down factor of 0 disables removing workers, which can be beneficial for autoscaling a single job. Bounds: [0.0, 1.0].

Declaration

public readonly double ScaleDownFactor

Field Value

Type	Description
System.Double

ScaleDownMinWorkerFraction

Minimum scale-down threshold as a fraction of total cluster size before scaling occurs. For example, in a 20-worker cluster, a threshold of 0.1 means the autoscaler must recommend at least a 2 worker scale-down for the cluster to scale. A threshold of 0 means the autoscaler will scale down on any recommended change. Bounds: [0.0, 1.0]. Default: 0.0.

Declaration

public readonly double? ScaleDownMinWorkerFraction

Field Value

Type	Description
System.Nullable<System.Double>

ScaleUpFactor

Fraction of average pending memory in the last cooldown period for which to add workers. A scale-up factor of 1.0 will result in scaling up so that there is no pending memory remaining after the update (more aggressive scaling). A scale-up factor closer to 0 will result in a smaller magnitude of scaling up (less aggressive scaling). Bounds: [0.0, 1.0].

Declaration

public readonly double ScaleUpFactor

Field Value

Type	Description
System.Double

ScaleUpMinWorkerFraction

Minimum scale-up threshold as a fraction of total cluster size before scaling occurs. For example, in a 20-worker cluster, a threshold of 0.1 means the autoscaler must recommend at least a 2-worker scale-up for the cluster to scale. A threshold of 0 means the autoscaler will scale up on any recommended change. Bounds: [0.0, 1.0]. Default: 0.0.

Declaration

public readonly double? ScaleUpMinWorkerFraction

Field Value

Type	Description
System.Nullable<System.Double>
