This error message indicates that the Spark containers failed to launch on the worker instances for the cluster, which can happen for a number of reasons, including issues with the underlying infrastructure or configuration issues. Here are some steps you can take to troubleshoot and resolve the issue:

1. Check the status of the worker instances in your cluster. Make sure that they are all up and running and that there are no issues with the underlying infrastructure. You can also check the logs of the worker instances to see if there are any errors or issues that might be causing the problem.
2. Check the configuration of your cluster. Make sure that the configuration is correct and that there are no errors or inconsistencies. You can also try changing the configuration and see if that resolves the issue.
3. Try restarting the cluster. Sometimes, restarting the cluster can resolve the issue. Make sure to save any important data before restarting the cluster.

It's also worth noting that if the run duration is still the same as if the notebook did run, it's possible that the notebook did actually run and complete, but the logs were not saved due to the error.
