Hit a bump while upgrading from Titan 0.4.0 to Titan 0.4.1. This was working just fine when using Titan 0.4.0

Looks like I am unable to get my scripts to be recognized by Rexster.

titan-server-0.4.1 $vi conf/rexster-cassandra-es.xml

             <imports>com.tinkerpop.gremlin.*,com.tinkerpop.gremlin.java.*,....truncated rest for readibility..</imports>
             <static-imports>com.tinkerpop.blueprints.Direction.*,com.tinkerpop.blueprints.TransactionalGraph$Conclusion.*,..truncated rest for readability....</static-imports>

titan-server-0.4.1 $cat scripts/data_types.groovy

def makeKey(g, name, dataType, indexed, unique){
  def k =  g.makeKey(name).dataType(Class.forName("java.lang.${dataType}"))
      k =  k.indexed(Vertex.class)
    k = k.unique()
  k = k.make()
    return k

def makeLabel(g, name, sortKey) {
  def l = g.makeLabel(name)
      l = l.sortKey(g.getType(sortKey))
  l = l.make()
    return l

Looks like some pathing has changed in the packaging between 0.4.0 and 0.4.1. I assume you had your scripts directory in TITAN_HOME. It looks like Titan Server is now looking for them in TITAN_HOME/rexhome. if you move your scripts directory there it should work.

@dalaro was this an intentional change going into 0.4.1?

Thanks. I'll try and see if it fixes it. Will report back

@spmallette I made that change intentionally to work around Rexster's log4j configuration. Here's my related comment in our conversation on #463: #463 (comment)


Yup...now I remember that. thanks. I've updated the wiki to reflect the change.

I can also confirm it is working by moving the scripts to rexhome. BTW, where did you look to figure out that the path has changed? Helps me troubleshoot next time

Rexster server logs were showing where it was looking for the script.
