Create a cluster

1. Go to the Alibaba Cloud CDP console.

2. On the Overview page, click Purchase CDP Product in the upper-right corner.

3. On the CDP purchase page, complete the cluster configurations.

   1. Software configuration

      Configuration item	Description
      Region	The cluster is created in the selected region. The region cannot be changed after the cluster is created.
      Kerberos authentication	Enables Kerberos authentication for the cluster. This feature is disabled by default. This feature is usually not required for individual user clusters.
      Default installed services	Services installed by default when the cluster is created. Select services as needed.

   2. Hardware configuration

      Configuration item	Description
      Billing method	Subscription: An upfront payment model.
      Subscription duration	Select a subscription duration as needed.
      Zone	Zones are distinct physical locations within a region. Service interconnection is enabled between zones. You can usually use the default zone.
      Virtual private cloud (VPC)	A virtual private cloud (VPC) is an isolated network environment that you build on Alibaba Cloud. VPCs are logically isolated from each other. You can customize the network topology and IP addresses. This option is for users who require high network security and have network management skills.
      vSwitch	Select a vSwitch in the zone of the corresponding VPC. If no vSwitch is available in the zone, create a new one.
      Security group	An existing security group is selected by default. You can also click Create Security Group to create a new one.
      Cluster high availability	Disabled by default. If you enable high availability (HA), the Master nodes are distributed across different underlying hardware to reduce the risk of failure.
      Instances	Master instance: Deploys services such as HDFS NameNode, YARN ResourceManager, and ZooKeeper Server. Core instance: Used for data storage and computation. Runs HDFS DataNode and YARN NodeManager. Utility instance: Deploys CM (the management component of CDP), Hive Metastore, Hue, and cluster metadata. For more information and configuration details, see Instance types and Configuration guide.

   3. Basic configuration
