Release 8.2

To access a Databricks cluster for running jobs, each user of the Trifacta® platform must insert their personal access token into their profile. This configuration enables the user to authenticate to a connected Databricks cluster.


NOTE: Each user must insert a personal access token into their profile. Users that do not provide a personal authentication token cannot run jobs on Databricks, including transformation, sampling, and profiling jobs.


NOTE: When you reset your personal access token (PAT), a new cluster is created if your new token does not have access to your current cluster. If you are resetting an expired personal access token, no new cluster is created. This new cluster is created when you first request access to the Databricks cluster. When you next use an interface that require access to the cluster, such as the relational browser, it may take some time to load.
