Hi, Jimmy,
Later today, when I call the API from my developer env. I got an error
"Internal Error:java.lang.IllegalStateException: Graph has been shut down",
Also when I run the GenTester, I got an error. Could you please help me check?

But I checked my environment, I didn't see any abnormal things.
Do you know how to start the graph? The graph here do not means the titan
database, is that right?
I restarted the titan, the log shows bellow:
root@ubuntu:/home/titan-1.0.0-hadoop1# sudo ./bin/titan.sh start
Forking Cassandra...
Running `nodetool statusthrift`... OK (returned exit status 0 and printed
string "running").

Run gremlin.sh to connect.
When I run gremlin.sh, the log shows as follows:
