it must configuration issue, encounter same issues?

thanks in advance!

at last, solved myself!

because had not choice, check source code, know little java/scala.

i found host:linux,port:9100 broker socket information, should print ip address. thought must wrong host.

then change configuration server.properties, host.name field ip , restart them, works well!
