Use Dataproc Hub

Create a Dataproc JupyterLab cluster from Dataproc Hub

1. Select the User-Managed Notebookstab on the Dataproc→Workbench page in the Google Cloud console.

2. Click Open JupyterLabin the row that lists the Dataproc Hub instance created by the administrator.

   1. If you do not have access to the Google Cloud console, enter the Dataproc Hub instance URL that an administrator shared with you in your web browser.

3. On the Jupyterhub→Dataproc Optionspage, select a cluster configuration and zone. If enabled, specify any customizations, then click Create.

   

   After the Dataproc cluster is created, you are redirected to the JupyterLab interface running on the cluster.

Create a notebook and run a Spark job

1. On the left panel of the JupyterLab interface, click on GCS (Cloud Storage).

2. Create a PySpark notebook from the JupyterLab launcher.

   

3. The PySpark kernel initializes a SparkContext (using the sc variable). You can examine the SparkContext and run a Spark job from the notebook.

   rdd = (sc.parallelize(['lorem', 'ipsum', 'dolor', 'sit', 'amet', 'lorem'])
          .map(lambda word: (word, 1))
          .reduceByKey(lambda a, b: a + b))
   print(rdd.collect())

   

4. Name and save the notebook. The notebook is saved and remains in Cloud Storage after the Dataproc cluster is deleted.

Shut down the Dataproc cluster

1. From the JupyterLab interface, select File→Hub Control Panelto open the Jupyterhubpage.

2. Click Stop My Clusterto shut down (delete) the JupyterLab server, which deletes the Dataproc cluster.
