启动gremlin - server服务时报如下异常：

解决问题 思路一

异常中提到了不存user这个顶点的Label。而这个label需要存在用户名密码信息。所以需要预告创建好user这个label。

过程 登陆gremlin console

依次执行：
cd ${JanusGraph}
./bin/gremlin.sh

在gremlin console中添加user的Label

依次执行：
graph = JanusGraphFactory.open('conf/janusgraph-berkeleyje.properties')
g = graph.traversal()
mgmt = graph.openManagement()
mgmt.makeVertexLabel('user').make()
mgmt.commit()
如果创建错了，可以使用以下语句删除该Label
mgmt.getVertexLabel('user').remove()

验证

仍然发现还是报同样的错，并且，注释掉authentication用户名密码配置后，便不在报错了。

思路二

跟据验证的情况，在gremlin console中添加user的label操作是不可取的，因为这个label会在服务启动时自动创建好。

（待解决补充，目前暂注释掉配置了）
