Crea un cluster Dataproc utilizzando gcloud CLI
Questa pagina mostra come utilizzare lo strumento a riga di comando Google Cloud CLI
gcloud per creare un cluster Dataproc, eseguire un job Apache Spark nel cluster, quindi modificare il numero di worker nel cluster.

In the Google Cloud console, on the project selector page,
select or create a Google Cloud project.
L'output del comando conferma la creazione del cluster:
Waiting for cluster creation operation...done.
Created [... example-cluster]
Per informazioni sulla selezione di una regione, vedi
Regioni e zone disponibili.
Per visualizzare un elenco delle regioni disponibili, puoi eseguire il
comando gcloud compute regions list.
Per saperne di più sugli endpoint a livello di regione, consulta
Endpoint a livello di regione.
Invia un job
Per inviare un job Spark di esempio che calcola un valore approssimativo per pi, esegui il
seguente comando:
