Can't connect to spark using 1.0.2 on Databricks 11.3 #587
Comments
How is it related to Spline? |
The only change in my workflow is upgrading the spline spark agent from 0.7.13 to 1.0.2, which makes it seems like it's a bug with the spark agent |
Can it be a coincidence? From the logs it looks like there's a connectivity issue, seemingly unrelated to Spline. Can you please double check that it works without Spline agent, but fails with it?

Yes, I've checked that the cluster successfully connects with no spline agent loaded and with spline agent v0.7.13 |
I am not able to replicate this. I used What if you start the cluster first and then install the agent? |
For our use case, we're using the spline agent bundle and a custom wrapper. We load both from jars and set the necessary config variables with an init script I can successfully start a cluster and then load the two libraries as jars, but that doesn’t set any config variables, so it doesn’t seem to be using them to capture lineage. A little testing shows that the cluster starts if I include our wrapper jar in the init script, but does not start if I include the spline agent jar in the init script |
Can you share your script please? It would help a lot if we could replicate the issue on our side. |

The script is setting Could you comment out the custom

That's an interesting point. It has worked in the past without doing so. Maybe because
I tried that and set the dispatcher to |
I wonder if it's not caused by a classpath conflict or any other unwanted runtime anomaly caused by a number of xbeans, service provides and other extra stuff I see the newer Spline bundle jar contains in comparison to the 0.7.x one. |
@afgaron can you try this bundle and let us know if it works please? |
Yes, I was able to start a cluster on 11.3 using that bundle! |
Awesome! Starting 1.0.4 release then. |
I use the spark agent to capture lineage on Databricks. I updated to v1.0.2 and am encountering an error on Databricks runtime 11.3; it works fine on 10.4. During cluster initialization, the endpoint fails to connect to the spark master. Trace:
