Required. The number of running instances for the node group to maintain. The group adds or removes instances to maintain the number of instances specified by this parameter.
requestId
string
Optional. A unique ID used to identify the request. If the server receives two ResizeNodeGroupRequest with the same ID, the second request is ignored and the first google.longrunning.Operation created and stored in the backend is returned.
Optional. Timeout for graceful YARN decommissioning. Graceful decommissioning allows the removal of nodes from the Compute Engine node group without interrupting jobs in progress. This timeout specifies how long to wait for jobs in progress to finish before forcefully removing nodes (and potentially interrupting jobs). Default timeout is 0 (for forceful decommission), and the maximum allowed timeout is 1 day. (see JSON representation of Duration).
Only supported on Dataproc image versions 1.2 and higher.
parentOperationId
string
Optional. operation id of the parent operation sending the resize request
Response body
If successful, the response body contains an instance of Operation.
