Administration Tools Metadata

The Administration Tools configuration data (metadata) contains information that databases need to start, such as the hostname/IP address of each participating host in the database cluster.

To facilitate hostname resolution within the Administration Tools, at the command line, and inside the installation utility, Vertica enforces all hostnames you provide through the Administration Tools to use IP addresses:

Metadata is more portable because Vertica does not require the names of the hosts in the cluster to be exactly the same when you install or upgrade your database.
