The number of retries that have been attempted to run a task if the first attempt fails. These notebooks provide functionality similar to that of Jupyter, but with additions such as built-in visualizations using big data, Apache Spark integrations for debugging and performance monitoring, and MLflow integrations for tracking machine learning experiments. If you want to cause the job to fail, throw an exception. %run command invokes the notebook in the same notebook context, meaning any variable or function declared in the parent notebook can be used in the child notebook. The safe way to ensure that the clean up method is called is to put a try-finally block in the code: You should not try to clean up using sys.addShutdownHook(jobCleanup) or the following code: Due to the way the lifetime of Spark containers is managed in Databricks, the shutdown hooks are not run reliably.
