Janusgraph: Receiving errors while starting janusgraph server(0.3.1)

[anukul-mohil]

I'm trying to setup janusgraph in remote server mode with gremlin server using Configure JanusgraphServer for HTTP
I got the following errors while trying to run the server:

and http-janusgraph-cql-configurationgraph.properties is:

graph.graphname=ConfigurationManagementGraph
storage.hostname=127.0.0.1
storage.username=cassandra_username
storage.password=cassandra_pass
storage.cql.keyspace=janusgraphtest

The first error goes away if the graphManager: org.janusgraph.graphdb.management.JanusGraphManager is added to http-gremlin-server.yaml
Though I'm not sure if that was required why was this not mentioned in the Configure JanusgraphServer for HTTP. So want to double check that too.
But the second error gremlin-groovy is not an available GremlinScriptEngine is preventing the server to start.

Janusgraph version: 0.3.1

Let me know if you need more information.
Any help is appreciated.
Thanks.

scripts/empty-sample.groovy defines a binding over the default graph 'graph' which is not available. You need to update or remove scripts/empty-sample.groovy from your configuration.
// define the default TraversalSource to bind queries to - this one will be named "g".
// globals << [g : graph.traversal()]

[zhangxiang17]

clear that array of scriptEngines.gremlin-groovy.plugins.org.apache.tinkerpop.gremlin.jsr223.ScriptFileGremlinPlugin.files , and restart your gremlin-server

[chupman]

To prevent confusion we have recently added a default template for new issues containing the guidelines as to what belongs in issues. Usage, configuration, and general questions should be asked in gitter, stackoverflow, or the janusgraph-users google group. Github issues are for reporting bugs, requesting new features, and tracking the development of JanusGraph. If your issue is still outstanding please consult one of the communities mentioned. If you still feel like your issue belongs here and was closed in error please feel free to repoen it.

[blindenvy]

@chupman I wonder if this is not a valid bug? This configuration is shipped with Janusgraph. Shouldn't sample configurations work out of the box?

[chupman]

@blindenvy, this was part of a mass cleanup of questions. It seemed more like a configuration issue than a bug to me. If this can be recreated it should definitely be reopened and diagnosed.

Please tell me how to fix these problems:
