             Summary: Zookeeper discovery split brain detection shouldn't consider client
nodes
                 Key: IGNITE-8422
                 URL: https://issues.apache.org/jira/browse/IGNITE-8422
             Project: Ignite
          Issue Type: Bug
          Components: zookeeper
    Affects Versions: 2.5
            Reporter: Pavel Kovalenko
            Assignee: Pavel Kovalenko
             Fix For: 2.6


Currently Zookeeper discovery checks each splitted cluster on full connectivity taking into
account client nodes. This is not correct, because server and client nodes may use different
networks to connect to each other. It means that there can be client which sees both parts
of splitted cluster and breaks split brain recovery - full connected part of server nodes
will be never find.

We should exclude client nodes from split brain analysis and improve split brain tests to
make them truly fair.
