Admin users of the Trifacta® platform can change settings through the Trifacta application. Login as an admin user, and click the Gear icon. Select Admin Settings.
Do not modify settings through the Admin Settings page and through
at the same time. Saving changes in one interface wipes out any unsaved changes in the other interface. Each requires a platform restart to apply the changes.
Platform administrators can change any parameter value that is available through the web application. Enter some or all of parameter name into the search box to see a set of possible matches.
Do not modify parameters with which you are unfamiliar or have not been instructed to change. Some changes can be harmful to the system. In particular, changing the database connection parameters can break access to the application and the Admin Settings page.
Tip: You can copy setting names from the documentation to search the available set. Search retrieves matches from the setting name and the help text for the parameter. Do not paste in double quotes from documentation samples.
If your search for a parameter comes up empty and you know that the parameter exists, you must make changes on the Trifacta node in
. See Required Platform Configuration.
If you search for the following strings, which may appear in property descriptions, you can review groups of settings pertaining to the configuration areas listed below.
NOTE: Do not perform configuration of these areas by simply reviewing and modifying the settings in these parameter groups. Additional configuration may be required. Some required settings may not be grouped, and some of these settings may not be documented. Please review the related documentation sections.
|Search string||Setting group|
|Core platform settings.|
Settings pertaining to specific Hadoop distributions.
|Settings that affect how the platform interacts with the integrated backend cluster. See Prepare Hadoop for Integration with the Platform.|
|Settings pertaining to integration with the Hadoop cluster's instance of Hive. See Configure for Hive.|
Settings pertaining to integration with cluster high availability for the Trifacta platform. See Enable Integration with Cluster High Availability.
|General settings pertaining to security. See Configure Security.|
|Settings pertaining to SSL access to the platform. See the SSL section in Configure Security.|
When you modify a setting, your change is validated against the data type or set of accepted values. String-based entries cannot be validated.
Sensitive information is obfuscated in the display values in the Admin Settings page.
To save changes, click Save.
NOTE: Saving changes forces an automatic type validation of the configuration and a restart of the platform, which terminates any active user sessions.
NOTE: Environmental validation is not performed as part of changes in this user interface. For example, you can change the port number for the Trifacta application to an invalid value and save the configuration change. However, when the platform is restarted, the application fails to start, and you cannot continue. In this case, you must fix the problem in
External Service Settings
AWS EMR Cluster ID
If you have deployed your instance of the Trifacta platform on to Amazon Web Services (AWS) and are connected to an Elastic Map Reduce (EMR) cluster, you can review or modify the cluster identifier in this location. For example, in the event of prolonged outage or failure of the original cluster, you can insert the cluster ID of a secondary cluster to effectively failover to the new cluster.
NOTE: When you first install and integrate with an EMR cluster, this identifier is stored in the Trifacta database for you. It should be modified only if you need to switch to a different EMR cluster. Only one EMR cluster can be active at any time.
NOTE: If this cluster ID is modified, you must modify any other EMR-related settings to match the corresponding values for the new cluster. Please search for
emr among the admin settings.
When you have entered a new cluster ID, click Save.
NOTE: For this setting, you do not have to click the Save button at the bottom of the screen, which restarts the Trifacta platform.
You can manage aspects of user accounts through the Admin Settings page. See Manage Users.
You can review overall status of the Trifacta platform.
Tricheck performs a variety of tests of your environment to determine its suitability for use with the Trifacta platform.
Tip: Tricheck should be run immediately after the Trifacta software has been installed or upgraded or whenever there are significant changes to the node or its connected cluster.
Checks include but are not limited to:
- Sufficient hardware resources on the Trifacta node
- Supported versions of software installed on the Trifacta node
- Access to required ports and all nodes of the cluster
- Trifacta node system profiling
NOTE: Tricheck performs no data-dependent checking. It cannot assess suitability of the environment for specific data volumes, connections, or data types.
Click Run Tricheck to run checks and download the output log.
Click Restart Trifacta to immediately restart the platform.
Tip: The Restart Trifacta button is the preferred method for restarting the platform. A restart is automatically executed when you save changes to the platform settings.
