When hosts configured incorrectly, causing problems not connect services
Mainly to solve the following problem:
I have two machines, machine name and ip as follows:
```
           ip hostname
192.168.1.1 host11
192.168.1.2 host12
```
I start gremlin-server on 192.168.1.1, and then access on 192.168.1.2.
But for some reason, the hosts file on the 192.168.1.2 is not configured
correctly, as follows:
`192.168.1.1 host33`
So I'm on the 192.168.1.2, it will report an error when accessing the
gremlin-server. My statement is as follows access
```
  Builder builder = Cluster.build ( "192.168.1.1");
  Cluster cluster = builder.create ();
  Client client = cluster.connect ();
  ResultSet results = client.submit ( "[1,2,3,4]");
  results.stream () forEach (System.out :: println).;
```
It reported the following error:
```
Exception in thread "main" java.lang.RuntimeException:
