   The Ambari Stack Advisor assesses your cluster configuration and might alert you to configuration issues. Note that this is not related to SmartSense, and is simply what Ambari does upon adding any service. SmartSense never makes configuration changes to your cluster. No cluster services need to be restarted after installing SmartSense, and any configuration changes that are noticed should be reverted.

   If you have a kerberized cluster, you will be prompted for the KDC admin credentials during this step.

6. On the Review page, click Deploy to complete your SmartSense service installation.
7. Exit the wizard.

   	Note
   	When activity analyzer is installed, Ambari may prompt to restart HDFS, YARN, and AMS services in order for activity analyzer to be able to communicate with these services. To restart these services select Restart All Required from the ... drop-down menu.
