You can set up proxy user functionality if you want HttpFS to impersonate a user from a set of hosts, or to impersonate a user that belongs to a set of groups. When you configure proxy user functionality, the proxy user can perform “doAs” operations. Add configuration properties to the
core-site.xml files to configure proxy user functionality.
Add the following configuration properties to the
#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.
