[moesterheld]

Expected Behavior

Current Behavior

Deprecated format for transport.publish_address is used, deprecation warning is shown in the logs:

transport.publish_address was printed as [ip:port] instead of [hostname/ip:port]. This format is deprecated and will change to [hostname/ip:port] in a future version. Use -Dopensearch.transport.cname_in_publish_address=true to enforce non-deprecated formatting.
