Index is failed to be built when specifying secure admin port 18091 on the nodes.
Sometimes Sysadmin block port 8091 due to security reasons.
Hence this issue is not allowing this systems to create an index on a specific node.
- make sure port 18091 is accessible
- make sure you have query and index service on that node
- try to create an index while specifying the secure port
- Index create fails
5. it works with specifying port 8091.
It is failing with 6.5.0 and 6.0.3, I haven't checked for earlier releases but I guess it is failing as well.
