The hostname will not be saved for the node and will not be used by the cluster to identify the node. This has been fixed. For more information about managing hostnames, see Section 2.4, “Using Hostnames with Couchbase Server”.
Installation and Upgrade
The 2.1.1 READMEs for the Server contain the wrong version number and are labeled 2.1.0 instead of 2.1.1. Ignore this oversight.
