Creating a Cluster

The first step of using MRS is to create a cluster. This section describes how to create a cluster on the MRS management console.

Procedure

  1. Log in to the MRS console.
  2. Click Create Cluster, the Create Cluster page is displayed

    When creating a cluster, pay attention to quota notification. If a resource quota is insufficient, increase the resource quota as prompted and create a cluster.

  3. On the page for create a cluster, click the Custom Config tab.
  4. Configure cluster software information.

    • Region: Use the default value.
    • 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.
    • Cluster Version: Select the latest version, which is the default value.
    • Cluster Type: Use the default Analysis Cluster.
    • Component Port: Use the default Open source.
    • Component: Select components such as Spark2x, HBase, and Hive for the analysis cluster. For a streaming cluster, select components such as Kafka and Storm. For a hybrid cluster, you can select the components of the analysis cluster and streaming cluster based on service requirements.

  5. Click Next.

    • AZ: Use 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.
    • Security Group: Select Auto create.
    • EIP: Select Bind later.
    • Enterprise Project: Use the default value.
    • Instance Specifications: Select General Computing S3 -> 8 vCPUs | 16 GB (s3.2xlarge.2) for both Master and Core nodes.
    • System Disk: Select Common I/O and retain the default settings.
    • Data Disk: Select Common I/O and retain the default settings.
    • Instance Count: The default number of Master nodes is 2, and that of Core nodes is 3.

  6. Click Next. The Set Advanced Options tab page is displayed. Configure the following parameters. Retain the default settings for the other parameters.

    • Kerberos authentication:
      • Kerberos Authentication: Disable Kerberos authentication.
      • Username: name of the Manager administrator. admin is used by default.
      • Password: password of the Manager administrator.
    • Login Mode: Select a mode for logging in to an ECS.
      • Password: Set a password for logging in to an ECS.
      • Key Pair: Select a key pair from the drop-down list. Select "I acknowledge that I have obtained private key file SSHkey-xxx and that without this file I will not be able to log in to my ECS." If you have never created a key pair, click View Key Pair to create or import a key pair. And then, obtain a private key file.
    • Secure Communications: Select Enable.

  7. Click Apply 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.

    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.
