Quickstart with Databricks

OpenLineage's Spark Integration can be installed on Databricks leveraging init scripts. Please note, Databricks on Google Cloud does not currently support the DBFS CLI, so the proposed solution will not work on Google Cloud until that feature is enabled.

Enable OpenLineage​

Follow the steps below to enable OpenLineage on Databricks.

  • Build the jar via Gradle or download the latest release.
  • Configure the Databricks CLI with your desired workspace:
  • Run upload-to-databricks.sh or upload-to-databricks.ps1. This will:
    • create a folder in DBFS to store the OpenLineage jar.
    • copy the jar to the DBFS folder
    • copy the init script to the DBFS folder
  • Create an interactive or job cluster with the relevant Spark configs:
    spark.openlineage.transport.type console
    spark.extraListeners io.openlineage.spark.agent.OpenLineageSparkListener
    spark.openlineage.version v1
  • Create manually open-lineage-init-script.sh through Workspace section in Databricks UI. Paste the script content from this file.
  • Make the cluster init script to point to previously created file. For example, if you create open-lineage-init-script.sh within Shared, then init scripts should point to /Shared/open-lineage-init-script.sh. User's workspace may be used as well. Alternatively, init script can be located in S3. Please mind that DBFS located init script are no longer supported (starting September 2023).
info

Please note that the init script approach is currently obligatory to install OpenLineage on Databricks. The Openlineage integration relies on providing a custom extra listener class io.openlineage.spark.agent.OpenLineageSparkListener that has to be available on the classpath at the driver startup. Providing it with spark.jars.packages does not work on the Databricks platform as of August 2022.

Verify Initialization​

A successful initialization will emit logs in the Log4j output that look similar to the following:

YY/MM/DD HH:mm:ss INFO SparkContext: Registered listener io.openlineage.spark.agent.OpenLineageSparkListener

YY/MM/DD HH:mm:ss INFO OpenLineageContext: Init OpenLineageContext: Args: ArgumentParser(host=https://YOURHOST, version=v1, namespace=YOURNAMESPACE, jobName=default, parentRunId=null, apiKey=Optional.empty) URI: https://YOURHOST/api/v1/lineage

YY/MM/DD HH:mm:ss INFO AsyncEventQueue: Process of event SparkListenerApplicationStart(Databricks Shell,Some(app-XXX-0000),YYYY,root,None,None,None) by listener OpenLineageSparkListener took Xs.

Create a Dataset​

Open a notebook and create an example dataset with:

spark.createDataFrame([
    {'a': 1, 'b': 2},
    {'a': 3, 'b': 4}
]).write.mode("overwrite").saveAsTable("default.temp")

Observe OpenLineage Events​

To troubleshoot or observe OpenLineage information in Databricks, see the Log4j output in the Cluster definition's Driver Logs.

The Log4j output should contain entries starting with a message INFO ConsoleTransport that contain generated OpenLineage events:
