4. 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 flavor of database to be used for Hive metastore or Oozie metastore, or Sqoop. (Currently, gsInstaller supports MySQL and Oracle databases).
FQDN of your database host name.
If you are using Oracle database, ensure that you have credentials for the database system user.
