Before You Begin

This 10-minute tutorial shows you how to create an Oracle Big Data Cloud (BDC) cluster on Oracle Cloud Infrastructure region.

Background

Oracle Big Data Cloud combines open source technologies such as Apache Spark and Apache Hadoop to deliver a complete Big Data platform for running and managing Big Data Analytics applications.

Oracle Big Data Cloud leverages Oracle’s Infrastructure Cloud Services to deliver a secure, elastic, integrated platform for all Big Data workloads.

You can create Oracle Big Data Cloud clusters in Oracle Cloud Infrastructure and in Oracle Cloud Infrastructure Classic. The infrastructure a cluster gets created in depends on the region you select when you create the cluster. If you see the Availability Domain and Subnet fields when you select a region for the cluster you're creating, that means the cluster will be created in Oracle Cloud Infrastructure. Otherwise, the cluster is created in Oracle Cloud Infrastructure Classic.

What Do You Need?

• Access to Oracle Cloud My Services. See How to Begin with Oracle Big Data Cloud Subscriptions
• Access to Oracle Big Data Cloud Service
• The required networking and storage resources in Oracle Cloud Infrastructure. See Creating the Infrastructure Resources Required for Oracle Platform Services

Start the Instance-Creation Wizard

1. Sign in to Oracle Cloud My Services.
2. On the My Services Dashboard page, locate the Big Data Cloud tile. Click the Action menu , and select Open Service Console.

   If this is the first time that you're accessing the web console of Oracle Java Cloud Service, the Welcome page is displayed. You can continue to the web console by clicking Go to Console.

3. The Instances page is displayed. Click Create Instance.

   

Configure Basic Cluster Information

On the Instance page of the wizard, complete the following steps:

1. Enter a unique Instance Name for your Big data Cloud instance.
2. Enter your email address in the Notification Email field.
3. In the Region field, select an Oracle Cloud Infrastructure region: us-phoenix-1, us-ashburn-1, eu-frankfurt-1, or uk-london-1. The field shows only those regions that are in the default region of your account.
4. In the Availability Domain field, select an availability domain.
5. In the Subnet field, select a subnet from a virtual cloud network (VCN) that you had created previously in Oracle Cloud Infrastructure. Note: If you want the subnet to be assigned automatically, then select Select No Preference.
6. Click Next.

   

Configure Service Details

On the Service Details page of the wizard, complete the following steps:

1. In the Cluster Configuration section, leave the Deployment Profile, Number of Nodes, Compute Shape, Queue Profile, and Spark Version fields at the default values.

   

2. In the Credentials section, click Edit next to the SSH Public Key field.
3. Select Create a New Key and then click Enter. In the Download Keys dialog box, click Download and save the file sshkeybundle.zip to your local machine.

   Note: The option to download the SSH keys won't be available again. You'll need the private key to SSH to the compute nodes of the Big Data Cloud instance. So don't skip this step.

4. Click Done.
5. Enter the Administrative User Name and Password, and then reenter the password in the Confirm Password field.

   

6. In the Associations section, select the Cloud Service that you want to associate with your Oracle Big Data Cloud cluster.
7. In the Cloud Storage Credentials section,enter the following values:
• OCI Cloud Storage URL: enter OCI Cloud Storage URL. For example:https://objectstorage.us-phoenix-1.oraclecloud.com
• OCI Cloud Storage Bucket URL: enter the URL of the object-storage bucket that you created earlier in Oracle Cloud Infrastructure.
  Format: oci://bdcsce@mytenancy/
  
• OCI Cloud Storage User OCID: enter the Oracle Cloud Infrastructure Object Storage User OCID. For example:
  ocid1.tenancy.oc1..aaaaaaaaba3pv6wkcr4jqae5f44n2b2m2yt2j6rx32uzr4h25vqstifsfdsq
• OCI Cloud Storage PEM Key: click Browse and select the OCI Cloud Storage PEM Key. Note: In Big Data Cloud, the PEM key must be created without a password.
• OCI Cloud Storage PEM Key Fingerprint:  enter the OCI Cloud Storage PEM Key Fingerprint.
  

  

8. In the Block Storage Settings, specify the amount of HDFS storage, you want to allocate to the cluster. Click Next.

Complete the Instance Creation

1. On the Confirm page of the wizard, review your selections, and click Create.

   

2. In the Oracle Big Data Cloud instances page, the new cluster is displayed, with the status Creating Service. Refresh the page periodically, until the instance is created.

   

   After the instance is created, you'll receive a notification at the email address that you specified earlier.
3. To view details of the instance, click the cluster name.
