Hi All - I have a graph that I'd like to add an index to.  I've tried it through gremlin with a smaller graph and the procedure works fine.  With a larger graph, however, I get a timeout error:

gremlin> mgmt.updateIndex(mgmt.getGraphIndex("fullNameIndex"),SchemaAction.REINDEX).get()

Any ideas?  I've also tried this through Java code, but I get a different error:
