For the last few hours, I have been trying to get our casual cluster up and running. Core nodes aren't starting, they are stuck at the following line -
Attempting to connect to the other cluster members before continuing...
These are our settings in the config file -
causal_clustering.cluster_allow_reads_on_followers=false causal_clustering.minimum_core_cluster_size_at_formation=3 causal_clustering.discovery_type=LIST causal_clustering.initial_discovery_members=172.x.x.x:5000,172.x.x.x:5000,172.x.x.x:5000
The debug logs say that all the nodes are in communication with each other. Master is elected too, but I see the following log in both non master nodes, which I think could be causing the problem -
2019-07-16 20:29:29.112+0000 DEBUG [com.hazelcast.internal.partition.InternalPartitionService] [172.x.x.x]:5000 [dev] [3.7.5] Master version should be greater than ours! Local version: 1129, Master version: 1129 Master: [172.x.x.x]:5000
We are running on 3.4.0 version of Neo4j. I can provide any other missing info if necessary.
Is there anyway for me to go about understanding what is the exact problem here and how to start the core servers?, Please help.
