Summary: GraphSONMessageSerializerGremlinV1d0 broken
Key: TINKERPOP-1732
URL: https://issues.apache.org/jira/browse/TINKERPOP-1732
Project: TinkerPop
Issue Type: Bug
Components: driver
Affects Versions: 3.2.5
Reporter: Robert Dale
Assignee: stephen mallette
If I configured gremlin-server.yaml with
{noformat}
serializers:
- { className:
org.apache.tinkerpop.gremlin.driver.ser.GraphSONMessageSerializerGremlinV1d0,
config: { ioRegistries:
[org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerIoRegistryV1d0] } }
# application/vnd.gremlin-v1.0+json
{noformat}
And configure a remote client like so
{noformat}
conf/remote.properties:
gremlin.remote.remoteConnectionClass=org.apache.tinkerpop.gremlin.driver.remote.DriverRemoteConnection
gremlin.remote.driver.clusterFile=conf/remote.yaml
gremlin.remote.driver.sourceName=g
conf/remote.yaml:
hosts: [localhost]
port: 8182
serializer: { className:
org.apache.tinkerpop.gremlin.driver.ser.GraphSONMessageSerializerGremlinV1d0,
config: { ioRegistries:
[org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerIoRegistryV1d0] } }
{noformat}
Then I connect with the client and get this error:
{noformat}
gremlin> graph = EmptyGraph.instance(); g =
graph.traversal().withRemote('conf/remote.properties')
==>graphtraversalsource[emptygraph[empty], standard]
gremlin> g.V()
