Enable Impersonation for Oozie

About this task

To enable impersonation for Oozie:

Add the following configuration properties to the oozie-site.xml file:

oozie.service.ProxyUserService.proxyuser.#USER#.hosts

oozie.service.ProxyUserService.proxyuser.#USER#.groups
Replace #USER# with the username of the proxy that can perform "doAs" operations. For the host property, you can add a list of host names as the value. For the group property, you can add a list of groups as the value. Alternatively, you can add a wildcard character (*) as the value for host and group properties. To add multiple users, copy the property and replace #USER# with the proxy user name.
Host Example:
```
<property>
                            <name>oozie.service.ProxyUserService.proxyuser.mapr.hosts</name>
                            <value>*</value>       
                            </property>
```
Group Example:
```
<property>
                            <name>oozie.service.ProxyUserService.proxyuser.mapr.groups</name>
                            <value>*</value>        
                            </property>
```
