5. Collect Information

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

The fully qualified domain name (FQDN) for each host in your system, and the components you want to set up on each host. You can use hostname -f to check for the FQDN.
If you install Hive/HCatalog, you need the hostname, database name, username, and password for the metastore instance.
Note
If you are using an existing instance, the dbuser you create for HDP must be granted ALL PRIVILEGES on that instance.
