> Depending on the order of entries in /etc/hosts, TestCLI can fail. This is because it
sets fs.default.name to "localhost", and then the bound IPC socket on the NN side reports
its hostname as "foobar-host" if the entry for 127.0.0.1 lists "foobar-host" before "localhost".
This seems to be the default in some versions of Ubuntu.
