Quickly Buying an MRS Cluster

MRS consists of multiple big data components, and you can select the cluster type that best fits your service requirements, data types, reliability expectations, and resource budget.

This section uses an HBase query cluster as an example to describe how to quickly buy an MRS cluster. An HBase cluster uses Hadoop and HBase components to provide a column-oriented distributed cloud storage system featuring enhanced reliability, great performance, and elastic scalability. It applies to the storage and distributed computing of massive amounts of data. You can use HBase to build a storage system capable of storing TB- or even PB-level data. With HBase, you can filter and analyze data with ease and get responses in milliseconds, rapidly mining data value.

Procedure

  1. Go to the Buy Cluster page.
  2. On the displayed page, click the Quick Config tab.
  3. Configure basic cluster information by referring to the following table.

    Table 1 MRS cluster parameters

    Parameter

    Description

    Example Value

    Billing Mode

    Billing mode of a cluster. MRS provides two billing modes: yearly/monthly and pay-per-use.

    Pay-per-use: If you select this mode, a certain deposit will be frozen. For details, see Billing Description.

    Pay-per-use

    Region

    Region where the resource to be created is located. Resources located in different regions cannot communicate with each other using an internal network. To improve access speed and reduce network latency, choose a region that is close to your own.

    -

    Cluster Name

    MRS cluster name. You can use the default name. However, you are advised to include a project name abbreviation or date for consolidated memory and easy distinguishing.

    After a cluster is created, you can change the cluster name in the cluster list.

    Cluster Type

    Select a proper MRS cluster type based on service requirements.

    • Analysis cluster: It is used for offline data analysis and comprises data analysis tools like Hadoop, Spark, HBase, Hive, Flink, Oozie, and Tez.
    • Streaming cluster: It processes streaming data to quickly analyze real-time data sources, and it mainly includes streaming data processing tools such as Kafka and Flume.
    • Hybrid cluster: It is suitable for both offline data analysis and stream processing.
    • Custom: You can select from a variety of components that are supported by the corresponding version of the MRS cluster.

    Custom

    Version Type

    MRS provides two cluster version types: LTS and Normal. Different version types provide different components. You can select a version type as required.

    • LTS: employs MRS's own components to provide highly reliable clusters with strong DR capabilities, making long-term support and evolution possible.
    • Normal: integrates MRS's mature and stable features and functions with open-source capabilities, offering high performance and stability. Currently, MRS clusters of the normal version type cannot be purchased directly. If you want to use clusters of this type, submit a service ticket.

    LTS

    Cluster Version

    Version of the MRS cluster. Different versions may contain different open-source component versions and functions. You are advised to select the latest version. For details about the lifecycle of each cluster version, see MRS Cluster Version Lifecycle.

    MRS 3.2.0-LTS.1

    Component

    Cluster templates containing preset components you will need for your business.

    NOTE:

    Hadoop components include HDFS, YARN, and MapReduce. Components used within a cluster, such as DBService, KrbServer, and LdapServer, are not displayed in the component list during cluster creation.

    HBase Query Cluster

    AZ

    AZ to which resources to be created belong in the current region. An AZ is a physical area where resources use independent power supply and networks.

    AZ1

    VPC

    VPC to which the MRS cluster node belongs. If no VPC is available, click View VPC to access the network console and create a VPC.

    For more information about VPCs, see What Is Virtual Private Cloud?

    -

    Subnet

    Subnet information in the VPC. If no subnet is available, click View Subnet to access the network console and create a subnet.

    For more information about subnets, see Subnet.

    -

    Cluster Node

    Specifications and quantity of nodes in an MRS cluster.

    For MRS 3.x or later, the memory of the Master node must be greater than 64 GB.

    Set the number of cluster nodes and node specifications as required.

    Kerberos Authentication

    Whether to enable Kerberos authentication for each component in the MRS cluster. If Kerberos authentication is enabled, users can access component resources only after being authenticated.

    This option cannot be changed after you buy a cluster.

    Kerberos authentication enabled

    Username

    Default user for logging in to MRS Manager and nodes in the MRS cluster. User admin is used to log in to MRS Manager, while user root is used to log in to the OS of nodes in the cluster.

    -

    Password/Confirm Password

    Passwords required for the root and admin users. The passwords are user-defined and must be kept secure.

    -

    Enterprise Project

    An enterprise project facilitates project-level management and grouping of cloud resources and users. You can select the system-defined enterprise project default or create a new one.

    default

    Required Duration

    Cluster subscription duration. This parameter is valid in Yearly/Monthly billing mode. The minimum cluster duration is 1 month and the maximum available cluster duration is 1 year.

    If Auto-renew is selected, monthly subscriptions are automatically renewed every month and yearly subscriptions are automatically renewed every year.

    -

    Secure Communications

    To allow the MRS console to access big data components in your VPC, you need to enable relevant security group rules to allow traffic to pass. For details, see Configuring Secure Communication Authorization for an MRS Cluster.

    Select the check box.

  4. Click Buy Now.

    If Kerberos authentication is enabled for a cluster, check whether Kerberos authentication is required. If yes, click Continue. If no, click Back to disable Kerberos authentication and then create a cluster. This option cannot be changed after you buy a cluster.

    For any doubt about the pricing, click Pricing details in the lower left corner.

  5. Click Back to Cluster List to view the cluster status. Click Access Cluster to view cluster details.

    For details about cluster status during creation, see the description of the status parameters in Table 1.

    It takes some time to create a cluster. The initial status of the cluster is Starting. After the cluster has been created successfully, the cluster status becomes Running.

    On the MRS console, a maximum of 10 clusters can be created concurrently, and a maximum of 100 clusters can be managed.
