Oracle Big Data cloud combines open source technologies to deliver a
complete Big Data Platform for running and managing Big Data Analytics
applications. Sign in to Oracle Cloud My Services. 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 accessing Oracle Big Data cloud, a
welcome screen appears. If this happens, continue to the console
by clicking Go to Console. The Oracle Big Data cloud instances page is
displayed. This page displays all the clusters on Oracle Big Data Cloud, and
enables you to create a cluster. To create a cluster click create instance.
On the first page of the Create New Instance wizard, provide a unique
Instance Name to identify the instance in your identity domain, an optional
cluster description, a notification email, and a region. For the region field, select
region to create the instance on Oracle Cloud Infrastructure. Select an
availability domain. Select a subnet from a virtual cloud network. Select available
tags for assignment or define new tags and assign to the instance. Then, click
Next. Configure your cluster by providing the
values in the Service Details page. Provide the cluster configuration
parameters. Specify: the deployment profile; the total number of nodes, three
or more nodes to provide high availability with multiple master nodes;
the number of Oracle compute units and amount of memory for each compute node
of the new cluster; and how you want to manage the queues in workload. Preemption
Off indicates that jobs can't consume more resources than a specific queue
allows. This will lead to potentially lower cluster utilization. Preemption On
indicates that jobs can consume more resources than a queue allows. Specify
the SPARC version to be deployed on the cluster. SPARC 1.6 or 2.1. Next, provide
your credentials. Associate an SSH key to this Cluster.
Click the edit button to choose SSH key file. Select create a New Key option to
create and download a new public key for this cluster. Assign an administrator
username for the cluster. Enter and re-enter a password for the
administrator. The association section enables you to associate your new
cluster with other cloud services. Select the Cloud Service that you want to
associate with your cluster. The Oracle Storage Cloud Service Container is where
the job logs are pushed upon completion. You can specify an existing storage
container. or create a new one. If you have an existing container, enter the
credentials. Provide the OCI object storage URL. Provide the URL of an
existing bucket in object storage. Provide the user
OCID. Generate the PEM key. Generate the PEM key fingerprint. Specify the
amount of HDFS storage you want to allocate to the cluster. Oracle Big Data
cloud uses a replication factor of two for HDFS. This means the usable HDFS
storage will be roughly half of the total allocated storage. Click Next. On
the confirmation page, review your selections and click create. In the
Oracle Big Data cloud Instances page, the new instance is displayed, with the
status Creating Service. Usually cluster creation takes some time. Once the
cluster is created the status disappears. Click Manage this instance menu, and
select Big Data Cloud Console. Enter your cloud console password credentials. Here,
you can create and execute jobs which read input from HDFS, Oracle database, or
Oracle Storage Cloud Service, perform computations on the data, and provide
output. You can also create and execute notes within the Notebook page. Notes
allows you to explore and visualize data in an iterative fashion. Find out more at
