janusgraph 默认server使用手记

启动server（with Cassandra/ES）

janusgraph-0.3.0-hadoop2 bin/janusgraph.sh start
Forking Cassandra...
Running `nodetool statusthrift`. OK (returned exit status 0 and printed string "running").
Forking Elasticsearch...
Connecting to Elasticsearch (127.0.0.1:9200)...... OK (connected to 127.0.0.1:9200).
Forking Gremlin-Server...
Connecting to Gremlin-Server (127.0.0.1:8182)...... OK (connected to 127.0.0.1:8182).
Run gremlin.sh to connect.

测试（用:remote用连接，用:>提交命令）
