Step 2: Install Cloudera Runtime Using the Wizard

Proceed through the installation wizard to specify hosts, install and configure Cloudera Runtime, and more.

Log Into the Cloudera Manager Admin Console

  1. In a web browser, go to http://<server_host>:7180, where <server_host> is the FQDN or IP address of the host where the Cloudera Manager Server is running.
  2. Log into Cloudera Manager Admin Console. The default credentials are:

    Username: admin

    Password: admin

Upload License File

On the Upload License File page, you can select either the trial version of CDP Data Center or upload a license file:

  1. Choose one of the following options:
    • Upload Cloudera Data Platform License
    • Try Cloudera Data Platform for 60 days. The CDP Data Center trial does not require a license file, but the trial expires after 60 days.
  2. If you choose the CDP Data Center Edition Trial, you can upload a license file at a later time. Read the license agreement and click the checkbox labeled Yes, I accept the Cloudera Standard License Terms and Conditions if you accept the terms and conditions of the license agreement. Then click Continue.
  3. If you have a license file for CDP Data Center, upload the license file:
    1. Select Upload Cloudera Data Platform License.
    2. Click Upload License File.
    3. Browse to the location of the license file, select the file, and click Open.
    4. Click Upload.
    5. Click Continue.
  4. Click Continue to proceed with the installation.

    The Welcome page displays.

Welcome (Add Cluster - Installation)

The Welcome page of the Add Cluster - Installation wizard provides a brief overview of the installation and configuration procedure, as well as some links to relevant documentation.

Click Continue to proceed with the installation.

Cluster Basics

The Cluster Basics page allows you to specify the Cluster Name

For new installations, a Regular Cluster (also called a base cluster) is the only option. You can add a compute cluster after you finish installing the base cluster.

For more information on regular and compute clusters, and data contexts, see Virtual Private Clusters and Cloudera SDX.

Enter a cluster name and click Continue.

Specify Hosts

Choose which hosts will run Runtime and other managed services.
  1. To enable Cloudera Manager to automatically discover hosts on which to install Runtime and managed services, enter the cluster hostnames or IP addresses in the Hostnames field. You can specify hostname and IP address ranges as follows:
    Expansion Range Matching Hosts
    10.1.1.[1-4] 10.1.1.1, 10.1.1.2, 10.1.1.3, 10.1.1.4
    host[1-3].example.com host1.example.com, host2.example.com, host3.example.com
    host[07-10].example.com host07.example.com, host08.example.com, host09.example.com, host10.example.com

    You can specify multiple addresses and address ranges by separating them with commas, semicolons, tabs, or blank spaces, or by placing them on separate lines. Use this technique to make more specific searches instead of searching overly wide ranges. Only scans that reach hosts running SSH will be selected for inclusion in your cluster by default. You can enter an address range that spans over unused addresses and then clear the nonexistent hosts later in the procedure, but wider ranges require more time to scan.

  2. Click Search. If there are a large number of hosts on your cluster, wait a few moments to allow them to be discovered and shown in the wizard. If the search is taking too long, you can stop the scan by clicking Abort Scan. You can modify the search pattern and repeat the search as many times as you need until you see all of the expected hosts.
  3. Verify that the number of hosts shown matches the number of hosts where you want to install services. Clear host entries that do not exist or where you do not want to install services.
  4. Click Continue.

    The Select Repository screen displays.

Select Repository

The Select Repository page allows you to specify repositories for Cloudera Manager Agent and CDH and other software.

In the Cloudera Manager Agent section:

  1. Select either Public Cloudera Repository or Custom Repository for the Cloudera Manager Agent software.
  2. If you select Custom Repository, do not include the operating system-specific paths in the URL. For instructions on setting up a custom repository, see Configuring a Local Package Repository.

In the CDH and other software section:

  1. Select the repository type to use for the installation. In the Install Method section select one of the following:
    • Use Parcels (Recommended)

      A parcel is a binary distribution format containing the program files, along with additional metadata used by Cloudera Manager. Parcels are required for rolling upgrades. For more information, see Parcels.

    • Use Packages
      A package is a standard binary distribution format that contains compiled code and meta-information such as a package description, version, and dependencies. Packages are installed using your operating system package manager.
  2. Select the version of Cloudera Runtime or CDH to install. If you do not see the version you want to install:
    • Parcels – Click the Parcel Repository & Network Settings link to add the repository URL for your version. If you are using a local Parcel repository, enter its URL as the repository URL.

      Repository URLs for CDH 6 parcels are documented in CDH 6 Download Information

      Repository URLs for the Cloudera Runtime 7 parcels are documented in Cloudera Runtime Download Information

      After adding the repository, click Save Changes and wait a few seconds for the version to appear. If your Cloudera Manager host uses an HTTP proxy, click the Proxy Settings button to configure your proxy.

      Note that if you have a Cloudera Enterprise license and are using Cloudera Manager 6.3.3 or higher to install a CDH version 6.3.3 or higher, or a Cloudera Runtime version 7.0 or higher using parcels, you do not need to add a username and password or "@" to the parcel repository URL. Cloudera Manager will authenticate to the Cloudera archive using the information in your license key file. Use a link to the repository in the following format:
      https://archive.cloudera.com/p/cdh6/6.x.x/parcels/
      If you are using a version of CM older than 6.3.3 to install CDH 6.3.3 or higher parcels, you must include the username/password and "@" in the repository URL during installation or when you configure a CDH 6.3.3 or higher parcel repository. After you add the repository, click Save Changes and wait a few seconds for the version to appear. If your Cloudera Manager host uses an HTTP proxy, click the Proxy Settings button to configure your proxy.
    • Packages – If you selected Use Packages, and the version you want to install is not listed, you can select Custom Repository to specify a repository that contains the desired version. Repository URLs for CDH 6 version are documented in CDH 6 Download Information,

      If you are using a local package repository, enter its URL as the repository URL.

  3. If you selected Use Parcels, specify any Additional Parcels you want to install.
  4. Click Continue.

Select JDK

If you installed your own JDK version, such as Oracle JDK 8, in Step 2: Install Java Development Kit, select Manually manage JDK.

To allow Cloudera Manager to automatically install the OpenJDK on cluster hosts, select Install a Cloudera-provided version of OpenJDK.

To install the default OpenJDK that is provided by your operating system, select Install a system-provided version of OpenJDK.

After checking the applicable boxes, click Continue.

Enter Login Credentials

  1. Select root for the root account, or select Another user and enter the username for an account that has password-less sudo privileges.
  2. Select an authentication method:
    • If you choose password authentication, enter and confirm the password.
    • If you choose public-key authentication, provide a passphrase and path to the required key files.

    You can modify the default SSH port if necessary.

  3. Specify the maximum number of host installations to run at once. The default and recommended value is 10. You can adjust this based on your network capacity.
  4. Click Continue.

The Install Agents page displays.

Install Agents

The Install Agents page displays the progress of the installation. You can click on the Details link for any host to view the installation log. If the installation is stalled, you can click the Abort Installation button to cancel the installation and then view the installation logs to troubleshoot the problem.

If the installation fails on any hosts, you can click the Retry Failed Hosts to retry all failed hosts, or you can click the Retry link on a specific host.

If you selected the option to manually install agents, see Manually Install Cloudera Manager Agent Packages for the procedure and then continue with the next steps on this page.

After installing the Cloudera Manager Agent on all hosts, click Continue.

If you are using parcels, the Install Parcels page displays. If you chose to install using packages, the Inspect Cluster page displays.

Install Parcels

If you selected parcels for the installation method, the Install Parcels page reports the installation progress of the parcels you selected earlier. After the parcels are downloaded, progress bars appear representing each cluster host. You can click on an individual progress bar for details about that host.

After the installation is complete, click Continue.

The Inspect Cluster page displays.

Inspect Cluster

The Inspect Cluster page provides a tool for inspecting network performance as well as the Host Inspector to search for common configuration problems. Cloudera recommends that you run the inspectors sequentially:

  1. Run the Inspect Network Performance tool. You can click Advanced Options to customize some ping parameters.
  2. After the network inspector completes, click Show Inspector Results to view the results in a new tab.
  3. Address any reported issues, and click Run Again (if applicable).
  4. Click Inspect Hosts to run the Host Inspector utility.
  5. After the host inspector completes, click Show Inspector Results to view the results in a new tab.
  6. Address any reported issues, and click Run Again (if applicable).

If the reported issues cannot be resolved in a timely manner, and you want to abandon the cluster creation wizard to address them, select the radio button labeled Quit the wizard and Cloudera Manager will delete the temporarily created cluster and then click Continue.

Otherwise, after addressing any identified problems, select the radio button labeled I understand the risks, let me continue with cluster creation, and then click Continue.

This completes the Cluster Installation wizard and launches the Add Cluster - Configuration wizard.
