GraphSONMessageSerializerGremlinV1d0 broken
[ https://issues.apache.org/jira/browse/TINKERPOP-1732?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16094761#comment-16094761 ]
stephen mallette commented on TINKERPOP-1732:
---------------------------------------------
You can't {{withRemote()}} prior to GraphSON 2.0. The type information isn't there to support it properly. I think this should be closed.

> 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

> {noformat}
> Then I connect with the client and get this error:
> {noformat}
> gremlin> graph = EmptyGraph.instance(); g = graph.traversal().withRemote('conf/remote.properties')
