Creating jobs in Cloudera Data Engineering
A job in Cloudera Data Engineering (CDE) consists of defined configurations and resources (including application code). Jobs can be run on demand or scheduled.
In Cloudera Data Engineering (CDE), jobs are associated with virtual clusters. Before you can create a job, you must create a virtual cluster that can run it. For more information, see Creating virtual clusters.
- Navigate to the Cloudera Data Engineering Overview page by clicking the Data Engineering tile in the Cloudera Data Platform (CDP) management console.
- In the CDE Services column, select the service containing the virtual cluster where you want to create the job.
- In the Virtual Clusters column on the right, click the View Jobs icon on the virtual cluster where you want to create the application.
- In the left hand menu, click Jobs.
- Click the Create Job button.
- Provide the Job Details:
- Select Spark for the job type. For Airflow job types, see Automating data pipelines using Apache Airflow DAG files in Cloudera Data Engineering.
- Specify the Name.
- Select File or
URL for your application file, and
provide or specify the file. You can upload a new file or select a
file from an existing resource.If you select URL and specify an Amazon AWS S3 URL, add the following configuration to the job:
- If your application code is a JAR file, specify the Main Class.
- Specify arguments if required. You can click the Add Argument button to add multiple command arguments as necessary.
- Enter Configurations if needed. You can click the Add Configuration button to add multiple configuration parameters as necessary.
- If your application code is a Python file, select the Python Version, and optionally select a Python Environment.
- Click Advanced Configurations to display
more customizations, such as additional files, initial executors,
executor range, driver and executor cores and memory.By default, the executor range is set to match the range of CPU cores configured for the virtual cluster. This improves resource utilization and efficiency by allowing jobs to scale up to the maximum virtual cluster resources available, without manually tuning and optimizing the number of executors per job.
- Click Schedule to display scheduling
options.You can schedule the application to run periodically using the Basic controls or by specifying a Cron Expression.
- If you provided a schedule, click Schedule to create the job. If you did not specify a schedule, and you do not want the job to run immediately, click the drop-down arrow on Create and Run and select Create. Otherwise, click Create and Run to run the job immediately.
