Hi, since the upgrade from 7.3.2 to 7.4.0, i see many errors of:
[WARN ][o.e.d.t.TransportInfo ] [es-data001.tab.com] 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 -Des.transport.cname_in_publish_address=true to enforce non-deprecated formatting.
[WARN ][o.e.d.h.HttpInfo ] [es-data001.tab.com] es.http.cname_in_publish_address system property is deprecated and no longer affects http.publish_address formatting. Remove this property to get rid of this deprecation warning.
Hmm, yes, I also see this now that I'm setting my publish host like yours. Do you need to set your network.publish_host to a host name like that? You normally don't need to set network.bind_host or network.publish_host at all.
Thanks @stefws, I think that is consistent with the issue mentioned above, and a fix will be available in 7.4.1. This other thread has a temporary workaround for 7.4.0 if the warnings are intolerable, but otherwise I'd recommend leaving it alone and upgrading when the fix is released.
