Returns
getGracefulDecommissionTimeout()
public Duration getGracefulDecommissionTimeout()
Required. 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].
.google.protobuf.Duration graceful_decommission_timeout = 5 [(.google.api.field_behavior) = REQUIRED];
| Type | Description |
| Duration | The gracefulDecommissionTimeout.
|
getGracefulDecommissionTimeoutOrBuilder()
public DurationOrBuilder getGracefulDecommissionTimeoutOrBuilder()
Required. 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].
.google.protobuf.Duration graceful_decommission_timeout = 5 [(.google.api.field_behavior) = REQUIRED];

Returns
Overrides
getScaleDownFactor()
public double getScaleDownFactor()
Required. Fraction of average YARN 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.
See How autoscaling
works
for more information.
Bounds: [0.0, 1.0].
double scale_down_factor = 2 [(.google.api.field_behavior) = REQUIRED];
| Type | Description |
| double | The scaleDownFactor.
|
getScaleDownMinWorkerFraction()
public double getScaleDownMinWorkerFraction()
Optional. 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.
double scale_down_min_worker_fraction = 4 [(.google.api.field_behavior) = OPTIONAL];
| Type | Description |
| double | The scaleDownMinWorkerFraction.
|
getScaleUpFactor()
public double getScaleUpFactor()
Required. Fraction of average YARN 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).
See How autoscaling
works
for more information.
Bounds: [0.0, 1.0].
double scale_up_factor = 1 [(.google.api.field_behavior) = REQUIRED];
| Type | Description |
| double | The scaleUpFactor.
|
getScaleUpMinWorkerFraction()
public double getScaleUpMinWorkerFraction()
Optional. 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.
double scale_up_min_worker_fraction = 3 [(.google.api.field_behavior) = OPTIONAL];
| Type | Description |
| double | The scaleUpMinWorkerFraction.

hasGracefulDecommissionTimeout()
public boolean hasGracefulDecommissionTimeout()
Required. 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].
.google.protobuf.Duration graceful_decommission_timeout = 5 [(.google.api.field_behavior) = REQUIRED];
