That is a misconception. To avoid split-brain, it is a good idea to set up master-only (data-less) nodes so they can not face heap problems. But that is not all, more important is to have at least three master eligible nodes, in case you get network disruptions. Additionally, you should set up at least two data nodes, otherwise your data is not fault tolerant against data loss if one server fails. Replica level 1 requires two data nodes.
