Hello,
I have 3 nodes and started to create a cluster.
1 master and 2 data
the problem is that I cannot connect the 3rd node (2nd data) at the cluster.
[root@elastic1 ~]# curl localhost:9200/_cat/nodes
172.27.52.56 22 70 4 0.00 0.09 0.14 di - data1
172.27.52.55 16 45 0 0.00 0.03 0.09 mi * master
the message I get at the 3rd node is:
Caused by: org.elasticsearch.transport.RemoteTransportException: [data2][172.27.52.57:9300][internal:cluster/coordination/join/validate]
Caused by: org.elasticsearch.cluster.coordination.CoordinationStateRejectedException: join validation on cluster state with a different cluster uuid 7UiHGr-tRNG2PPoJ6Po5Nw than local cluster uuid Tx77PhoRTv6KUsXkON5DGA, rejecting
the configurations of the nodes are the below:
