Hello everyone, i'm working on 3 vmwares with ubuntu 19

After successfully install and launch zookeeper server and compile RAMCloud, when i type this command:

$ obj.master/coordinator -C tcp:host=192.168.242.132,port=11100 -x zk:192.168.242.132:2181

I'm getting some errors that i don't found anywhere on the internet:

The relevant message from the log is this one:

couldn't find host 'openwhisk-invoker0', thrown at IpAddress at src/IpAddress.cc:64

Check to make sure the DNS resolves for that host on the machine you are trying this on.
