Instance Attribute Details
#graceful_decommission_timeout ⇒ String
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.
Corresponds to the JSON property gracefulDecommissionTimeout

#scale_down_factor ⇒ Float
Required. 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.
Corresponds to the JSON property scaleDownFactor

#scale_down_min_worker_fraction ⇒ Float
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.
Corresponds to the JSON property scaleDownMinWorkerFraction

#scale_up_factor ⇒ Float
Required. 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.
Corresponds to the JSON property scaleUpFactor

#scale_up_min_worker_fraction ⇒ Float
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.
Corresponds to the JSON property scaleUpMinWorkerFraction
