Adding the DAS Service through the Ambari UI

After you successfully install the DAS MPack through the Ambari console, add the DAS service through the Ambari UI.

  1. Launch the Ambari host in a browser and log in.
    http://<ambari-server-host>:8080
    The default credentials are:
    • Username: admin
    • Password: admin
  2. If you are using a local repository, then specify it in the dasbn-repo field.
    1. Go to Ambari > Admin > Stacks and Versions > Versions and click Show Details.
    2. On the Version Details pop-up, click the Edit Repositories icon.
    3. On the Repositories screen, specify the local repository URL in the dasbn-repo field and click Save.
  3. In the Ambari Services navigation pane, click Actions > Add Service.
    The Add Service Wizard is displayed.
  4. On the Choose Services page of the Wizard, select Data Analytics Studio.
    Other required services are automatically selected.
  5. When prompted to confirm addition of dependent services, give a positive confirmation to all.
    This adds the other required services.
  6. On the Assign Masters page, you can go ahead with the default settings.
  7. On the Customize Services page, expand Advance_data_analytics_studio-database and fill in the database details and other required fields that are highlighted.
    1. If you have installed Postgres database on your own, then:
      1. Uncheck Create Data Analytics Studio database.
      2. Set the database host in the Data Analytics Studio database hostname.
      3. Set the database username in Data Analytics Studio database username.
      Note
      Note
      The hostname is ignored if the Create Data Analytics Studio database option is checked, the database will be installed on the same host as the Webapp.
    2. Database Password - Enter the password.

    You can set credentials to whatever you want.

  8. If Hive SSL is enabled, set the Hive session params in DAS configuration as follows:
    sslTrustStore=/etc/security/serverKeys/hivetruststore.jks;trustStorePassword=your_password
  9. If Knox SSO is enabled, update admin_users under Advanced data_analytics_studio-security-site, with the list of users who need admin access to DAS.
    Note
    Note
    Only admin users have access to all the queries. Non-admin users can access only their queries.
  10. Complete the remaining installation wizard steps and exit the wizard.
  11. Ensure that all components required for your DAS service have started successfully.
  12. Make sure to restart all the affected services in Ambari.
