OrientDB - How to create a database on clustering servers?

I install two nodes with default configuration, cluster status:

"members": [{
    "id": "192.168.1.101:2434",
    "listeners": [{"protocol": "ONetworkProtocolBinary", "listen": "192.168.1.101:2424"}, {"protocol": "ONetworkProtocolHttpDb", "li
80"}],
    "alias": "192.168.1.101:2434",
    "status": "aligning"
    }, {
    "id": "192.168.1.102:2435",
    "listeners": [{"protocol": "ONetworkProtocolBinary", "listen": "192.168.1.101:2425"}, {"protocol": "ONetworkProtocolHttpDb", "li
80"}],
    "alias": "192.168.1.101:2435",
    "status": "aligning"
    }],
"name": "_hzInstance_1_orientdb",
"local": "192.168.1.101:2435"
}

      

        
        
        
      

    

but when I use Java API to connect to one server and try to create a database an exception is thrown,

admin = new OServerAdmin(PATH);
            admin.connect("root", "password");

            if (!admin.existsDatabase()) {
                admin.createDatabase("document", "local");
            }

Why is this happening? How can I rip the database on the clustering servers?

thank.
