Databricks - Run Job
In this article
Overview
You can use this Snap to automate the execution of a set of tasks or processes within a Databricks workspace. It triggers the task and periodically checks its progress. The Snap stops after the job is complete, but if you cancel the pipeline before the task finishes, the Snap requests to terminate the task.
Example
Run Job on a Cluster
The following example pipeline demonstrates how to run a job specified in the notebook on a cluster.Snap Type
The Databricks - Run Job Snap is a Write-type Snap.
Prerequisites

Example
Run Job on a Cluster
The following example pipeline demonstrates how to run a job specified in the notebook on a cluster.
Step 1: Configure the Databricks - Run Job Snap with the following settings:
a. Task name: Specify the task the Databricks - Run Job Snap must perform in this field.
b. Notebook path: Specify the path to the Databricks notebook that contains the code to be executed. This path indicates the location within the Databricks environment where the notebook is stored.
c. Cluster: Specify the cluster on which the job must be executed. The cluster configuration (including computational resources) is predefined and identified by this name and ID.
d. Interval check (seconds): Specify the frequency (in seconds) at which the Snap will check the status of the running job. In this case, it will check every 10 seconds.
