Venkata Phani Kumar Mangipudi updated TINKERPOP3-815:
-----------------------------------------------------
Description:
I've a titan 0.9.0-M2 running in server mode through a docker container
connecting to elasticsearch and cassandra containers. All the containers
running from a ubuntu linux 14.04.1 server. This gremlin-server is then exposed
via nginx for websocket and http connections.
Gremlin-server started without any errors in the log file.
I am able to connect to the gremlin server from postman client on another
windows desktop machine "http://titandb.in/gremlin?gremlin=100-1"; and get the
correct response.
But when I am trying to connect using gremlin-driver from a scala application,
I am not able to get through to the gremlin-server.
I could see following error in nginx error log:
2015/08/28 18:16:38 [error] 4478#0: *22964 connect() failed (111: Connection
refused) while connecting to upstream, client: 192.168.1.5, server:
dev.myserver.in, request: "GET /gremlin HTTP/1.1", upstream:
"http://[::1]:8182/gremlin";, host: "dev.myserver.in:80"
The gremlin-server.log file in the server shows following error message for the
connect() requests from gremlin-driver:
7466936 [gremlin-server-worker-1] WARN
org.apache.tinkerpop.gremlin.server.handler.HttpGremlinEndpointHandler -
Invalid request - responding with 400 Bad Request and no gremlin script supplied
Tried to connect to the server websockets from ubuntu server via curl command
as follows, but the websockets connection is not initiated:
$ curl -i -N -H "Connection: Upgrade" -H "Upgrade: websocket" -H "Host:
localhost" -H "Origin: http://localhost:8182";
http://localhost:8182/gremlin?gremlin=100-1
This results in the normal json response but doesn't start a websocket
connection.
if I am doing something wrong, please suggest a right direction
