Hello Ken, Indeed tickets and documentation are confusing so let me clarify what they are about.
Documentation at [1] and ticket IGNITE-1203 [2] are related to *TcpDiscoverySpi* component (see javadoc for in at [3]). More precisely they are about Zookeeper-based implementation of subcomponent called IpFinder which helps TcpDiscoverySpi to locate nodes of Ignite cluster. Ticket IGNITE-7222 [4] is about new implementation of *DiscoverySpi* interface (see [5]) based on Zookeeper. Most likely it will be released in Ignite 2.5. As per proposal page [6] it seems there is some mess with labels in JIRA because tickets listed on the page look unrelated to it. I'll try to fix the page so in won't confuse people.
