5. Collect Information

To deploy your HDP installation, you need to collect the following information:

  • The fully qualified domain name (FQDN) for each host in your system, and which component(s) you wish to set up on which host. You can use hostname -f to check for the FQDN if you do not know it.

  • The hostname (for an existing instance), database name, username, and password for the MySQL instance, if you install Hive/HCatalog.


If you are using an existing instance, the dbuser you create for HDP’s use must be granted ALL PRIVILEGES on that instance.
