can't get a titan graph instance from gremlin server

Question

I started two gremlin server in two different machines ,for distribute computing.

Here is part of gremlin-server.yaml

host: 192.168.200.115
port: 8182
threadPoolWorker: 3
gremlinPool: 6
scriptEvaluationTimeout: 30000
serializedResponseTimeout: 30000
channelizer: org.apache.tinkerpop.gremlin.server.channel.WebSocketChannelizer
graphs: {graph: conf/titan-cassandra-es.properties}
....

Here is part of titan-cassandra-es.properties

storage.backend=cassandrathrift
gremlin.graph=com.thinkaurelius.titan.core.TitanFactory
storage.hostname=192.168.200.115,192.168.200.116                                                                 
storage.cassandra.keyspace=titan                                                                         
storage.cassandra.replication-factor=3
....

It's all right when I started the gremlin server ,and connected to the gremlin server cluster:

gremlin> :remote connect tinkerpop.server conf/remote.yaml

==>Connected - dns121/192.168.200.116:8182, dns115/192.168.200.115:8182

But when I want to get the graph instance ,It's warning 'No such property: graph for class: groovysh_evaluate'.

gremlin> graph

No such property: graph for class: groovysh_evaluate

Display stack trace? [yN] n

But in this page, it shows we can use graph directly after we connected to a gremlin server cluster.

So question is ,Which part I'm missing ?

Your syntax is bad. You are evaluating "graph" locally in the console and not on the server. You need to include :submit with your command or as shown in the documentation you referenced :> (the shortcut for :sumbit).

gremlin> :> graph

That should fix your problem. Note that in later versions of TinkerPop you can put the "remote" into console mode with:

gremlin> :remote console

which allows you to omit the :>. You can read more about that here. That feature is not available on Titan 1.0 but thought I would mention it.
