Hi, I would suggest going through TopologyValidator implementations in test and check out something like: https://github.com/apache/ignite/blob/master/modules/core/src/test/java/org/apache/ignite/internal/processors/cache/IgniteTopologyValidatorGridSplitCacheTest.java
If you want to get the collection of alive baseline nodes, check out for this method: org.apache.ignite.internal.managers.discovery.DiscoCache#aliveBaselineNodes Note that this is internal API and is not exposed to be accessed publicly, but you can cast Ignite to IgniteEx and access it through calling: igniteEx.context().discovery().discoCache().aliveBaselineNodes(); Best regards, Anton -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
