Overview
The Google APIs Explorer is a tool that helps you explore various Google APIs interactively. With the APIs Explorer, you can:
Browse quickly through available APIs and versions.
See methods available for each API and what parameters they support along with inline documentation.
Execute requests for any method and see responses in real time.
Make authenticated and authorized API calls.
Search across all services, methods, and your recent requests to quickly find what you are looking for.
The APIs Explorer uses its own API key whenever it makes a request. When you use the APIs Explorer to make a request, it displays the request syntax, which includes a placeholder labeled {YOUR_API_KEY}. If you want to make the same request in your application, you need to replace this placeholder with your own API key.
In this lab, you'll learn how to use an inline Google APIs Explorer template to call the Cloud Dataproc API to create a cluster, then run a simple Spark job in the cluster. It also shows you how to use the APIs Explorer template to call the Cloud Dataproc API to update a cluster.
Setup and requirements
Read these instructions. Labs are timed and you cannot pause them. The timer, which starts when you click Start Lab, shows how long Google Cloud resources will be made available to you.
This hands-on lab lets you do the lab activities yourself in a real cloud environment, not in a simulation or demo environment. It does so by giving you new, temporary credentials that you use to sign in and access Google Cloud for the duration of the lab.
To complete this lab, you need:
- Access to a standard internet browser (Chrome browser recommended).
Note: Use an Incognito or private browser window to run this lab. This prevents any conflicts between your personal account and the Student account, which may cause extra charges incurred to your personal account.
- Time to complete the lab---remember, once you start, you cannot pause a lab.
Note: If you already have your own personal Google Cloud account or project, do not use it for this lab to avoid extra charges to your account.
How to start your lab and sign in to the Google Cloud console
Click the Start Lab button. If you need to pay for the lab, a pop-up opens for you to select your payment method. On the left is the Lab Details panel with the following:
The Open Google Cloud console button
Time remaining
The temporary credentials that you must use for this lab
Other information, if needed, to step through this lab
Click Open Google Cloud console (or right-click and select Open Link in Incognito Window if you are running the Chrome browser).
The lab spins up resources, and then opens another tab that shows the Sign in page.
Tip: Arrange the tabs in separate windows, side-by-side.
Note: If you see the Choose an account dialog, click Use Another Account.
If necessary, copy the Username below and paste it into the Sign in dialog.

You can also find the Username in the Lab Details panel.
Click Next.
Copy the Password below and paste it into the Welcome dialog.
FOq443Oral1H
You can also find the Password in the Lab Details panel.
Click Next.
Important: You must use the credentials the lab provides you. Do not use your Google Cloud account credentials.
Note: Using your own Google Cloud account for this lab may incur extra charges.
Click through the subsequent pages:
Accept the terms and conditions.
Do not add recovery options or two-factor authentication (because this is a temporary account).
Do not sign up for free trials.
After a few moments, the Google Cloud console opens in this tab.
Note: To view a menu with a list of Google Cloud products and services, click the Navigation menu at the top-left.
Activate Cloud Shell
Cloud Shell is a virtual machine that is loaded with development tools. It offers a persistent 5GB home directory and runs on the Google Cloud. Cloud Shell provides command-line access to your Google Cloud resources.
Click Activate Cloud Shell
at the top of the Google Cloud console.
When you are connected, you are already authenticated, and the project is set to your Project_ID, qwiklabs-gcp-04-5633370102d2. The output contains a line that declares the Project_ID for this session:
Your Cloud Platform project in this session is set to qwiklabs-gcp-04-5633370102d2
gcloud is the command-line tool for Google Cloud. It comes pre-installed on Cloud Shell and supports tab-completion.
- (Optional) You can list the active account name with this command:
gcloud auth list
- Click Authorize.
Output:
ACTIVE: *
ACCOUNT: student-04-fcca080921a0@qwiklabs.net
To set the active account, run:
$ gcloud config set account `ACCOUNT`
- (Optional) You can list the project ID with this command:
gcloud config list project
Output:
[core]
project = qwiklabs-gcp-04-5633370102d2
Note: For full documentation of gcloud, in Google Cloud, refer to the gcloud CLI overview guide.
Task 1. Open APIs Explorer
Go to Navigation menu > APIs & Services.
Scroll down the list until you find Cloud Dataproc API, and click on it.
Make sure that API is enabled, if not click Enable.
Now that you have verified the API's enablement, open Rest API Reference. This will open a new tab with the Rest API Reference page for the Cloud Dataproc API.
Task 2. Create a cluster
From the left APIs & Reference section navigate to REST reference > v1 > projects.regions.clusters > create to projects.regions.clusters.create method or, to create cluster, use the Method: projects.regions.clusters.create reference.
Now you'll fill in the form and execute the APIs Explorer template, below, as follows:
Insert your Qwiklabs Project ID in the projectId field.
Set the region field to us-central1.
In the Request body, click between the curly brackets and add the clusterName property. Enter the clusterName of your choice. Note, the value of the clusterName must not contain any uppercase letters or spaces.
