Getting Error while deploying Titan with TinkerTop at AWS EC2

[manoj nainwal]

Hi,

I am new for Gremlin as well as Titan.

I have directly downloaded titan from link - http://s3.thinkaurelius.com/downloads/titan/titan-1.0.0-hadoop1.zip .

unzip in Amazon EC2, and try to access it through my local browser. I got this error - {"message":"no serializer for requested Accept header: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8"}

After that I was searching for solution and find one link of google group. - https://groups.google.com/forum/#!msg/aureliusgraphs/v4UcYwE5UVU/4coljP_EBwAJ

So I have copied - cp conf/gremlin-server/gremlin-server.yaml conf/gremlin-server/rest-gremlin-server.yaml

and changes in new file -

host: 0.0.0.0

channelizer: org.apache.tinkerpop.gremlin.server.channel.HttpChannelizer

graphs: {
  graph: conf/gremlin-server/titan-cassandra-server.properties}

copy cp conf/titan-cassandra.properties conf/gremlin-server/titan-cassandra-server.properties

changes to this file -

storage.hostname=127.0.0.1
storage.cassandra.keyspace=TITAN_DEMO

started server - ./bin/gremlin-server.sh ./conf/gremlin-server/rest-gremlin-server.yaml

from browser - http://172.30.xx.xxx:8182/?gremlin=100-1, but got error.

What do I do ?

Help me to get out of this.

Thanks,

Manoj

Hey Manoj,

Did you ever get this working? I can seem to get my server started with the channelizer set to 

channelizer: org.apache.tinkerpop.gremlin.server.channel.WebSocketChannelizer

but not with 

channelizer: org.apache.tinkerpop.gremlin.server.channel.HttpChannelizer

It gets all the way to the end then says:

ERROR org.apache.tinkerpop.gremlin.server.GremlinServer  - Gremlin Server was unable to start and will now begin shutdown: Could not bind to localhost and 8182 - perhaps something else is bound to that address.

Do you know if I need to configure something different on my VPC and subnets if I am using the Http rather than websockets?

Any help would be greatly appreciated.

Regards,

Robbie
