Here are the startup logs for all three nodes:

Thanks for your help.

192.168.51.6 : giving IP as 192.168.51.1...can you please check /etc/hosts file of 192.168= .51.6 (might be 192= .168.51.1 is configured in /etc/hosts)

192.168.52.4 : datanode startup might be failed ( you can check this node l= ogs)
