In Strategy 10.x and 11.x, join cluster fails or doesn't work fine if two nodes don't know each other’s' machine name.
It is noticed that the Intelligence server hosted machine can't ping each other by machine name.
This is working as designed.
In Strategy cluster logic, Intelligence Server uses machine name to build the connection.
When setting up a new cluster environment, it is necessary to check whether the cluster node can ping another node successfully by machine name.
If the machine name is not recognized by another node, then join cluster will fail even if IP address is used to do the join.
Add the IP/machine name to host file.
