Logging vertex program
Hi Nikita, Do you use the spark web UI? In the executor tab you can follow the stderr link and see any logged or printed output. No idea why they use stderr. Best wishes, Marc

Hi Nikita, Sorry for asking the obvious, but are you sure you committed the addV() transaction with a g2.tx().commit() before closing the Gremlin Console? Best wishes, Marc

Hi Nikita, gremlin console does a lot of imports for you, but does not cover the full JanusGraph and TinkerPop APIs. So, sometimes you have to do an import yourself. In this case: gremlin> import org.
