### Impersonation
When Zeppelin server is running with authentication enabled, then this interpreter utilizes Hive's user proxy feature i.e. sends extra parameter for creating and running a session ("hive.server2.proxy.user=": "${loggedInUser}"). This is particularly useful when multi users are sharing a Notebook server.
To enable this set `zeppelin.jdbc.auth.type` as `SIMPLE` in the interpreter setting.
