We are using DataStax Enterprise version 5.0.1 and are facing issue while creating the graph from the Gremlin Console.
Here are the details of the error that I am getting:
adminuser@dc0vm1:~$ dse gremlin-console
\,,,/

gremlin> :> system.graph('food').create()
Host did not respond in a timely fashion - check the server status and submit again.
I changed the Remote.yaml file settings from [locahost] to hosts: [13.82.30.252].
I ran the nodetool command to check if the server is running properly:
adminuser@dc0vm1:~$ nodetool status

The cassandra.yaml has the following entries related to the host:
broadcast_rpc_address: 13.82.30.252
rpc_address: 0.0.0.0
Could you please let me know what configuration I am missing here?
I figured out that by default the DSE Graph service is not enabled so you need to edit the file "dse" to enable it -
sudo vim /etc/default/dse
Make sure that the following parameter is set to 1 –
# Enable the DSE Graph service on this node
GRAPH_ENABLED=1
Restart the DSE service -
sudo service dse stop
sudo service dse start
Now Gremlin Console is able to connect and create the Graph.
