      pip3 show jupyterlab

3. Install the Dataproc JupyterLab plugin.

   pip3 install dataproc-jupyter-plugin

   1. If your JupyterLab version is earlier than 4.0.0, enable the plugin extension.

      jupyter server extension enable dataproc_jupyter_plugin

4. Start JupyterLab.

   jupyter lab

   1. The JupyterLab Launcher page opens in your browser. It contains a Dataproc Jobs and Sessions section. It can also contain Dataproc Serverless Notebooks and Dataproc Cluster Notebooks sections if you have access to Dataproc serverless notebooks or Dataproc clusters with the Jupyter optional component running in your project.

      

      On MacOS, if you receive a SSL: CERTIFICATE_VERIFY_FAILED error in your terminal when you launch Jupyterlab, update your Python SSL certificate by executing /Applications/Python 3.11/Install Certificates.command. This file is located in the Python home directory.

   2. By default, your Dataproc Serverless for Spark Interactive session runs in the project and region you set when you ran gcloud init in Before you begin. You can change the project and region settings for your sessions from the JupyterLab Settings > Dataproc Settings page.

Create a Dataproc Serverless runtime template

Dataproc Serverless runtime templates (also called session templates) contain configuration settings for executing Spark code in a session. You can create and manage runtime templates using Jupyterlab or the gcloud CLI.

JupyterLab

1. Click the New runtime template card in the Dataproc Serverless Notebooks section on the JupyterLab Launcher page.

   

2. Fill in the Runtime template form.

   

3. Specify a Display name and Description, and then input or confirm the other settings.

   Notes:

   • Network Configuration: The subnetwork must have Private Google Access enabled and must allow subnet communication on all ports (see Dataproc Serverless for Spark network configuration).

     If the default network's subnet for the region you configured when you ran gcloud init in Before you begin is not enabled for Private Google Access:

     • Enable it for Private Google Access, or
     • Select another network with a regional subnetwork that has Private Google Access enabled. You can change the region that Dataproc Serverless uses from the JupyterLab Settings > Dataproc Settings page.

   • Metastore: To use a Dataproc Metastore service in your sessions, select the metastore project ID, region, and service.

   • Max idle time: The maximum notebook idle time before the session is terminated. Allowable range: 10 minutes to 336 hours (14 days).

   • Max session time: The maximum lifetime of a session before the session is terminated. Allowable range: 10 minutes to 336 hours (14 days).

   • PHS: You can select an available Persistent Spark History Server to allow you to access session logs during and after sessions.

     The PHS must be set up in location (region) where your sessions run. By default, Dataproc Serverless sessions run in the project and region set with the gcloud init command. You can change the project and region settings from the JupyterLab Settings > Dataproc Settings page.

   • Spark properties: Click Add Property for each property to set for your serverless Spark sessions. See Spark properties for a listing of supported and unsupported Spark properties, including Spark runtime, resource, and autoscaling properties.

   • Labels: Click Add Label for each label to set on your serverless Spark sessions.

4. View your runtime templates from the Settings > Dataproc Settings page.

   • You can delete a template from the Action menu for the template.

   

5. Click Save.

6. Open and reload the JupyterLab Launcher page to view the saved notebook template card on the JupyterLab Launcher page.

       idleTtl: 3600s
       ttl: 14400s
       stagingBucket: staging-bucket
     peripheralsConfig:
       metastoreService: projects/my-project-id/locations/us-central1/services/my-metastore-id
       sparkHistoryServerConfig:
         dataprocCluster: projects/my-project-id/regions/us-central1/clusters/my-cluster-id
   jupyterSession:
     kernel: PYTHON
     displayName: Team A
   labels:
     purpose: testing
   runtimeConfig:
     version: "1.1"
     containerImage: gcr.io/my-project-id/my-image:1.0.1
     properties:
       "p1": "v1"
   description: Team A Development Environment
   

   If the default network's subnet for the region you configured when you ran gcloud init in Before you begin is not enabled forPrivate Google Access:

   • Enable it for Private Google Access, or
   • Select another network with a regional subnetwork that has Private Google Access enabled. You can change the region that Dataproc Serverless uses from the JupyterLab Settings > Dataproc Settings page.

2. Create a session (runtime) template from your YAML file by running the following gcloud beta dataproc session-templates import command locally or in Cloud Shell:

   gcloud beta dataproc session-templates import TEMPLATE_ID \
       --source=YAML_FILE \
       --project=PROJECT_ID \
       --location=REGION
   

   • See gcloud beta dataproc session-templates for commands to describe, list, export, and delete session templates.

Launch and manage notebooks

After installing the Dataproc JupyterLab plugin, you can click template cards on the JupyterLab Launcher page to:

• Launch a Jupyter notebook on Dataproc Serverless.

• Launch a Jupyter notebook on a Dataproc on Compute Engine cluster.

Launch a Jupyter notebook on Dataproc Serverless

The Dataproc Serverless Notebooks section on the JupyterLab Launcher page displays notebook template cards that map to Dataproc Serverless runtime templates (see Create a Dataproc Serverless runtime template).

1. Click a card to create a Dataproc Serverless session and launch a notebook. When session creation is complete and the notebook kernel is ready to use, the kernel status changes from Unknown to Idle.

2. Write and test notebook code.

   1. Copy and paste the following PySpark Pi estimation code in the PySpark notebook cell, then press Shift+Return to run the code.

      import random
          
      def inside(p):
          x, y = random.random(), random.random()
          return x*x + y*y < 1
          
      count = sc.parallelize(range(0, 10000)) .filter(inside).count()
      print("Pi is roughly %f" % (4.0 * count / 10000))

      Notebook result:

      

3. After creating and using a notebook, you can terminate the notebook session by clicking Shut Down Kernel from the Kernel tab.

   • If you don't terminate the session, Dataproc terminates the session when the session idle timer expires. You can configure the session idle time in the runtime template configuration. The default session idle time is one hour.

Launch a notebook on a Dataproc on Compute Engine cluster

If you created a Dataproc on Compute Engine Jupyter cluster, the JupyterLab Launcher page contains a Dataproc Cluster Notebook section with pre-installed kernel cards.

To launch a Jupyter notebook on your Dataproc on Compute Engine cluster:

1. Click a card in the Dataproc Cluster Notebook section.

2. When the kernel status changes from Unknown to Idle, you can start writing and executing notebook code.

3. After creating and using a notebook, you can terminate the notebook session by clicking Shut Down Kernel from the Kernel tab.

Manage input and output files in Cloud Storage

Analyzing exploratory data and building ML models often involves file-based inputs and outputs. Dataproc Serverless accesses these files on Cloud Storage.

• To access the Cloud Storage browser, click the Cloud Storage browser icon in the JupyterLab Launcher page sidebar, then double-click a folder to view its contents.

  

• You can click Jupyter-supported file types to open and edit them. When you save changes to the files, they are written to Cloud Storage.

• To create a new Cloud Storage folder, click the new folder icon, then enter the name of the folder.

• To upload files into a Cloud Storage bucket or a folder, click the upload icon, then select the files to upload.

Develop Spark notebook code

After installing the Dataproc JupyterLab plugin, you can launch Jupyter notebooks from the JupyterLab Launcher page to develop application code.

PySpark and Python code development

Dataproc Serverless and Dataproc on Compute Engine clusters support PySpark kernels. Dataproc on Compute Engine also supports Python kernels.

• Click a PySpark card in the Dataproc Serverless Notebooks or Dataproc Cluster Notebook section on the JupyterLab Launcher page to open a PySpark notebook.

• Click on a Python kernel card in the Dataproc Cluster Notebook section on the JupyterLab Launcher page to open a Python notebook.

SQL code development

Click the PySpark kernel card in the Dataproc Serverless Notebooks or Dataproc Cluster Notebook section of the JupyterLab Launcher page to open a PySpark notebook to write and execute SQL code.

Spark SQL magic: Since the PySpark kernel that launches Dataproc Serverless Notebooks is preloaded with Spark SQL magic, instead of using spark.sql('SQL STATEMENT').show() to wrap your SQL statement, you can type %%sparksql magic at the top of a cell, then type your SQL statement in the cell.

BigQuery SQL: The BigQuery Spark connector allows your notebook code to load data from BigQuery tables, perform analysis in Spark, and then write the results to a BigQuery table.

The Dataproc Serverless 2.1 runtime includes the BigQuery Spark connector. If you use the Dataproc Serverless 2.0 or earlier runtime to launch Dataproc Serverless notebooks, you can install Spark BigQuery Connector by adding the following Spark property to your Dataproc Serverless runtime template:

spark.jars: gs://spark-lib/bigquery/spark-bigquery-with-dependencies_2.12-0.25.2.jar

Note: Install the BigQuery Spark connector on your Dataproc cluster, to use it with Dataproc Cluster Notebooks.

Scala code development

Dataproc on Compute Engine clusters created with image version 2.0+, 2.1+ and later, include Apache Toree, a Scala kernel for the Jupyter Notebook platform that provides interactive access to Spark.

• Click the Apache Toree card in the Dataproc Cluster Notebook section on the JupyterLab Launcher page to open a notebook for Scala code development.

  

Metadata explorer

If a Dataproc Metastore (DPMS) instance is attached to a Dataproc Serverless runtime template or a Dataproc on Compute Engine cluster, the DPMS instance schema is displayed in the JupyterLab Metadata Explorer when a notebook is opened. DPMS is a fully-managed and horizontally-scalable Hive Metastore (HMS) service on Google Cloud.

To view HMS metadata in the Metadata Explorer:

• Enable the Data Catalog API in your project.

• Enable Data Catalog sync in your DPMS service.

• Specify a DPMS instance when you create the Dataproc Serverless runtime template or create the Dataproc on Compute Engine cluster.

To open the JupyterLab Metadata Explorer, click its icon in the sidebar.

You can search for a database, table, or column in the Metadata Explorer. Click a database, table, or column name to view the associated metadata.
