Restart Affected Services
Verify "ranger_audits" is created in Ambari Infra Solr
Summary
Further Reading

Before we begin creating, assigning, and editing tag policies we must enable Ranger audit to Solr and start the services needed to assign policies. Additionally, we will stop services not necessary for this tutorial.

Furthermore, we should become acquainted with the personas who reside within the HDP Sandbox.

Here is a brief description of them:

raj_ops: Big Data Operations
maria_dev: Big Data Developer

Raj is our administrator and thus has full access to most of Ambari's services. Maria is our developer and thus has limited access to our cluster's services.

Username – raj_ops Password – raj_ops

Username – maria_dev Password – maria_dev

In order to set up our environment we will use our cluster administrator admin.

Enable Ranger Audit to Solr

Use your HDP admin credentials to sign in.

Table 1: Ambari Login credentials

Username	Password
admin	**your password

If this is your first time setting up the admin password follow the instructions in Setup Ambari Admin Password Manually.

Once in Ambari click on the Ranger service on the service Stack on the left and follow these steps to enable audit to Solr:

1. Ensure you are in the Ranger service

2. Select the Configs tab

3. Go to the Ranger Audit tab

4. Turn ON Ranger's Audit to Solr and SolrCloud features

5. Save this configuration

In the Save Configuration window that appears, write Enable Audit to Solr and SolrCloud Feature, then select Save, next click OK button on Dependent Configurations window. Finally, click Proceed Anyway on the Save Configuration Changes window, and click OK.

Stop Services Not Used in Tag Based Policies

Before we restart all the services that were affected by enabling the Audit to Solr and SolrCloud, we need to stop services that will not be used as part of the Tag Based Policies tutorial. We do this because we will be starting additional services, our sandbox is meant to have limited resources and might not respond well to having many services on at the same time.

We will start with Spark2. Go to the Spark2 service, click on the Stop button located in Service Actions.

1. Stop the following services in this order:

Spark2
Zeppelin

Restart Affected Services

Enabling Solr and SolrCloud affected other services on the stack. In order for the changes that we made to take effect on our sandbox we need to restart the affected services. We will start with Zookeeper.

Restart the Zookeeper Service

1. Select Zookeeper, then click on Service Actions. Click on Restart All to restart all components of Zookeeper. It will also restart all affected components of Zookeeper.

2. On the Confirmation window, press Confirm Restart All.

Background Operation Running window will appear showing Zookeeper currently is being restarted. This window will appear for other services you perform a service action upon.
