I am trying to setup janusgraph (latest version) with cassandra(3.11.5) and elastic seaarch(7.5.2) in Google compute engine using docker. When I run docker ps -a, all the containers are up and running. But when I am trying to update the schema I am facing the following errors:

gremlin-groovy is not an available GremlinScriptEngine
org.apache.tinkerpop.gremlin.jsr223.console.RemoteException: gremlin-groovy is not an available GremlinScriptEngine
        at org.apache.tinkerpop.gremlin.console.jsr223.DriverRemoteAcceptor.submit(DriverRemoteAcceptor.java:184)
        at org.codehaus.groovy.vmplugin.v7.IndyInterface.selectMethod(IndyInterface.java:234)

When I researched on the above error I found that if the Elastic search is not working there might be a chance of throwing this error. So I checked the status of the janusgraph by running the command bin/janusgraph.sh then I got following two errors

Gremlin-Server (org.apache.tinkerpop.gremlin.server.GremlinServer) is running with pid 31
Elasticsearch (org.elasticsearch.bootstrap.Elasticsearch) does not appear in the java process table
Cassandra (org.apache.cassandra.service.CassandraDaemon) does not appear in the java process table

Gremlin-Server is working fine but Elasticsearch and cassandra are not working. I found various articles regarding the above issue but none of them worked for me.

Here is my docker-compose.yml file:

You can see the commented lines for janusgraph volumes, I commented because those files are mounting as folders instead of files.

Is there any way to solve the above issues. Thanks in advance

  • cassandra writes its logs to /var/log/cassandra/system.log - check the file for errors – Alex Tbk Feb 12 '20 at 06:37
  • can you provide elasticsearch logs – anand Feb 12 '20 at 07:44
  • I added the cassandra and ealstic search links to janusgraph in docker-compose file and I updated hostnames in janusgraph-cql-es-server.properties and janusgraph-cassandra-es-server . It worked fine – rajashekar Feb 13 '20 at 04:49
