Hello Ken, Indeed tickets and documentation are confusing so let me clarify what they are about.
Documentation at  and ticket IGNITE-1203  are related to *TcpDiscoverySpi* component (see javadoc for in at ). More precisely they are about Zookeeper-based implementation of subcomponent called IpFinder which helps TcpDiscoverySpi to locate nodes of Ignite cluster. Ticket IGNITE-7222  is about new implementation of *DiscoverySpi* interface (see ) based on Zookeeper. Most likely it will be released in Ignite 2.5. As per proposal page  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.  https://apacheignite.readme.io/docs/cluster-config# zookeeper-based-discovery  https://issues.apache.org/jira/browse/IGNITE-1203  https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/spi/discovery/tcp/TcpDiscoverySpi.html  https://issues.apache.org/jira/browse/IGNITE-7222  https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/spi/discovery/DiscoverySpi.html  https://cwiki.apache.org/confluence/display/IGNITE/Discovery+SPI+by+ZooKeeper On Wed, Mar 7, 2018 at 1:46 PM, kcheng.mvp <kcheng....@gmail.com> wrote: > There is a section in the document > https://apacheignite.readme.io/docs/cluster-config# > zookeeper-based-discovery. > > but I found below two tickets. > > https://issues.apache.org/jira/browse/IGNITE-1203 > > https://issues.apache.org/jira/browse/IGNITE-7222 > > I am a bit confused about which version supports this feature. > > mean while I found there are 3 open issues in this wiki page. > > > https://cwiki.apache.org/confluence/display/IGNITE/ > Discovery+SPI+by+ZooKeeper > > > > > -- > Sent from: http://apache-ignite-developers.2346864.n4.nabble.com/ >
