Content Summary: This page outlines how to install and configure trusted third-party libraries for Databricks.
Specifying More than One Trusted Library
To specify more than one trusted library, comma delimit the URIs:
In the Databricks Clusters UI, install your third-party library .jar or Maven artifact with Library Source Upload, DBFS, DBFS/S3, or Maven. Alternatively, use the Databricks libraries API.
In the Databricks Clusters UI, add the IMMUTA_SPARK_DATABRICKS_TRUSTED_LIB_URIS property as a Spark environment variable and set it to your artifact's URI:
Maven Artifacts
For Maven artifacts, the URI is maven:/<maven_coordinates>, where <maven_coordinates> is the Coordinates field found when clicking on the installed artifact on the Libraries tab in the Databricks Clusters UI. Here's an example of an installed artifact:
In this example, you would add the following Spark environment variable:
.jar Artifacts
For jar artifacts, the URI is the Source field found when clicking on the installed artifact on the Libraries tab in the Databricks Clusters UI. For artifacts installed from DBFS or S3, this ends up being the original URI to your artifact. For uploaded artifacts, Databricks will rename your .jar and put it in a directory in DBFS. Here's an example of an installed artifact:
In this example, you would add the following Spark environment variable:
Restart the cluster.
Once the cluster is up, execute a command in a notebook. If the trusted library installation is successful, you should see driver log messages like this:
