Installing DAS on CDP Private Cloud Base using Cloudera Manager

You can install DAS using Cloudera Manager if you have transitioned from an Ambari-managed CDP Private Cloud Base cluster to a Cloudera Manager-managed cluster using the AM2CM tool, or if you were using Ambari Views on HDP 2.6.5 or DAS on HDP 3.1.5 and have upgraded to CDP Private Cloud Base 7.x.

Make sure that you have created a PostgreSQL database version 9.6, 10, or 12 to use with DAS. If you have an existing Postgres database that you used with DAS on HDP 3.1.5, then you can point DAS to the same database during the database setup stage, so that you do not lose saved queries and query history.

  1. Log in to Cloudera Manager as an Administrator.
  2. From the Cloudera Manager homepage, go to the Status tab, click the more options icon on your $Cluster Name click Add Service.
  3. On the Select Services page, select Data Analytics Studio and click Continue.
  4. On the Select Dependencies page, select the dependencies that you want to set up with DAS and click Next.
  5. On the Assign Roles page, select role assignments for your dependencies and click Continue.
  6. On the Setup Database page, specify the Postgres database name, database host, username, and password.
    Click Test Connection to validate the settings and click Continue.
    If the connection is successful, a green checkmark and the word Successful appears next to the service name. If there are any problems, an error is reported indicating that the service failed to connect.
  7. The Review Changes page lists default and suggested settings for several configuration parameters, including data directories.
    Select user authentication mode as None.
    Review and make any necessary changes, and then click Continue. The Command Details page is displayed.
  8. The Command Details page shows the status of your operation. After completion, you can view the installation logs under the standard output (stdout).
    After the First Run command completes, click Continue to go to the Summary page.
  9. The Summary page reports the success or failure of the setup wizard. Click Finish to complete the wizard. The installation is complete.
    If the DAS WebApp fails to start with the following error message, then specify the latest activated CDH 7.1.x parcel directory in the DAS WebApp Advanced Configuration Snippet:
    Error: Could not find or load main class org.apache.ranger.credentialapi.buildks.

    For more information, see Unable to start DAS after installing the GPL Extras parcel.
