Installing SmartSense in an Ambari Environment
Before you start the installation:
You should know your SmartSense ID and account name (both are available in the Hortonworks support portal in the Tools tab).
You must also ensure that an Ambari agent is running on the same host as the Ambari server.
To begin the installation, follow these steps:
If you are using Ambari 2.0 or 2.1, or a non-Ambari installation and want to use SmartSense 1.3.x, you must first download and install it (Downloading and Installing SmartSense Binary).
From the Ambari web UI, select from the drop-down menu.
From the list of installable services, select , and then click Next.
On the Assign Masters page, select cluster nodes for the HST server, Activity Analyzer, and Activity Explorer, and then click Next.
For a list of criteria to determine the best node to select for HST server, see the HST Server Placement section.
For a list of criteria to determine the best nodes to select for Activity Analyzers see the Activity Analyzer Placement section.
On the Customize Services page, validate the values in the following fields, as appropriate to your environment:
Ambari 2.1+
Ambari 2.0

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.
On the Review page, click to complete your SmartSense service installation.
Restart the Ambari server:
# ambari-server restart
