Apply a recommendation

While some recommendations can be applied automatically, others have to be applied manually.

There are two ways to tell how a recommendation can be applied:

When reviewing open recommendations, you can see in the Classifiers column, what options are available for which recommendation.
When reviewing a specific recommendation, you can see one of the two options: Mark As Applied (for recommendations that must be applied manually) or Proceed to Apply (for recommendations that must be applied automatically).

Automatically apply a recommendation

Applying a recommendation automatically involves the following tasks:

Steps

From the Recommendations page, click on the table row corresponding to the recommendation that you want to review.
Click on Proceed to Apply.
Review recommended changes.
Enter a comment in the Change Notes field. This comment will later allow you to track the Ambari configuration version created after applying a configuration.
Click on Apply.
You can optionally provide feedback for this recommendation and then click on Submit Feedback. Or you can opt out and click I will provide later. You can still provide feedback later, from the History page.
You can view the configuration change in Ambari configuration history.

Applying a recommendation manually involves the following tasks:

Steps

From the Recommendations page, click on the table row corresponding to the recommendation that you want to review.
Apply the recommendation manually.
Click on Mark As Applied.
Click on I have to confirm that you've applied the changes.

	Note
	You can revert previously applied recommendations. This option is available on the History page.
