Hi,
Yes, all the configurations are the same on all 5 nodes. I have checked
more than 10 times.
Before scaling , 3 node cluster was working fine, but scaling from 3 to 5
node, then we are facing this problem.
only question is on 3 node cluster it is working fine, but after scaling it
is not working and zkcli is not able to connect.
but one case I have seen.
1. if i remove all the SSL configuration from all the nodes and then
applying again all SSL property then it is working fine.
2 cases
1st case :- 3 node cluster witout SSL is working fine
scaled the cluster till 5 node without SSL is also
working fine
after that when applying SSL on all 5 nodes then it is
also working
2nd case :- 3 node cluster with SSL is working fine
scaled the cluster till 5 node with SSL is not working
in both cases the configuration area same and certificate is also same.
Thanks,
