Run Databricks notebooks

Before you can run any cell in a notebook, you must attach the notebook to a cluster.

To run all the cells in a notebook, select Run All in the notebook toolbar.

Important

Do not use Run All if steps for mount and unmount are in the same notebook. It could lead to a race condition and possibly corrupt the mount points.

To run a single cell, click in the cell and press shift+enter. You can also run a subset of lines in a cell or a subset of cells. See Run selected text and Run selected cells.

To run all cells before or after a cell, use the cell actions menu at the far right. Click and select Run All Above or Run All Below. Run All Below includes the cell you are in; Run All Above does not.

The behavior of Run All Above and Run All Below depends on the cluster that the notebook is attached to.

• On a cluster running Databricks Runtime 13.3 LTS or below, cells are executed individually. If an error occurs in a cell, the execution continues with subsequent cells.
• On a cluster running Databricks Runtime 14.0 or above, or on a SQL warehouse, cells are executed as a batch. Any error halts execution, and you cannot cancel the execution of individual cells. You can use the Interrupt button to stop execution of all cells.

When a notebook is running, the icon in the notebook tab changes from to . If notifications are enabled in your browser and you navigate to a different tab while a notebook is running, a notification appears when the notebook finishes.

To stop or interrupt a running notebook, select in the notebook toolbar. You can also select Run > Interrupt execution, or use the keyboard shortcut I I.

Notifications

Notifications alert you to certain events, such as which command is currently running and which commands are in error state. When your notebook is showing multiple error notifications, the first one will have a link that allows you to clear all notifications.

Notebook notifications are enabled by default. You can disable them in user settings.

Background notifications

If you start a notebook run and then navigate away from the tab or window that the notebook is running in, a notification appears when the notebook is completed. You can disable this notification in your browser settings.

Databricks Advisor

Databricks Advisor automatically analyzes commands every time they are run and displays appropriate advice in the notebooks. The advice notices provide information that can assist you in improving the performance of workloads, reducing costs, and avoiding common mistakes.

Click the Learn more link to view documentation providing more information related to the advice.

Click the Don’t show me this again link to hide the piece of advice. The advice of this type will no longer be displayed. This action can be reversed in Editor settings.
