Quickly Buying an HBase Query Cluster

This section describes how to quickly buy an HBase query cluster. The HBase cluster uses Hadoop and HBase components to provide a column-oriented distributed cloud storage system featuring enhanced reliability, excellent 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.

The HBase analysis cluster consists of the following components:

  • MRS 1.9.2: Hadoop 2.8.3, HBase 1.3.1, and Ranger 1.0.1.
  • MRS 3.1.0: Hadoop 3.1.1, HBase 2.2.3, ZooKeeper 3.5.6, and Ranger 2.0.0.
  • MRS 3.1.2-LTS.3: Hadoop 3.1.1, HBase 2.2.3, ZooKeeper 3.6.3, and Ranger 2.0.0.

Quickly Buying an HBase Query Cluster

  1. Log in to the MRS console.
  2. Click Buy Cluster. The page for buying a cluster is displayed.
  3. On the page for buying a cluster, click the Quick Config tab.
  4. Configure basic cluster information. For details about the parameters, see Buying a Custom Cluster.

    • Region: Use the default value.
    • Billing Mode: Select Pay-per-use.
    • 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, for example, mrs_20180321.
    • Version Type: Normal is selected by default. (Components vary depending on the version type. Select a version type as needed.)
    • Cluster Version: Select the latest version, which is the default value. (The components provided by a cluster vary according to the cluster version. Select a cluster version based on site requirements.)
    • Component: Select HBase Query Cluster.
    • AZ: Use the default value.
    • Enterprise Project: Retain the default value.
    • VPC: Use the default value. If there is no available VPC, click View VPC to access the VPC console and create a new VPC.
    • Subnet: Use the default value.
    • CPU Architecture: Use the default value. This parameter is unavailable in MRS 3.x.
    • Cluster Node: Select the number of cluster nodes and node specifications based on site requirements. For MRS 3.x or later, the memory of the master node must be greater than 64 GB.
    • Kerberos Authentication: Whether to enable Kerberos authentication. The slider status cannot be changed once the cluster is bought.
    • Username: The default value is root/admin. User root is used to remotely log in to ECSs, and user admin is used to access the cluster management page.
    • Password: Set a password for user root/admin.
    • Confirm Password: Enter the password of user root/admin again.

  5. Select Enable to enable secure communications. For details, see Communication Security Authorization.
  6. Click Buy Now.

    If Kerberos authentication is enabled, check whether this function is required. If it is, click Continue. If not, click Back to disable it and then proceed with the subsequent step. The slider status cannot be changed once the cluster is bought.

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

  7. 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 management console, a maximum of 10 clusters can be concurrently created, and a maximum of 100 clusters can be managed.
