我正在使用 titan/hbase 来存储我的数据，而 Titan 和 Hbase 驻留在远程服务器计算机中。我用bin/titan.sh start. 之后，我在服务器机器上运行了以下命令，效果很好：
bin/gremlin.sh

现在要检查远程连接，我只是gremlin.sh从客户端机器上运行并运行
gremlin> :remote connect tinkerpop.server conf/remote.yaml
g=TitanFactory.open("conf/titan-hbase.properties")
我得到以下信息：

我的 titan-hbase.properties 是：
storage.backend=hbase
storage.hostname=192.168.1.65
cache.db-cache-time = 180000
cache.db-cache = true
cache.db-cache-clean-wait = 20
cache.db-cache-size = 0.5
gremlin.graph=com.thinkaurelius.titan.core.TtanFactory
storage.hbase.tablename = titan
和 remote.yaml 是：
hosts: [192.168.1.65]
port: 8182
serializer: { className: org.apache.tinkerpop.gremlin.driver.ser.GryoMessageSerializerV1d0, config: { serializeResultToString: true }}
这里出了什么问题？我怎样才能做到这一点？
