Hive user impersonation should work irrespective of simple or kerberos hadoop cluster. Please refer to the documenation here.

Kerberos is for authentication purpose while doAs is for authorization. When doAs is set to true, the queries against Metastore and jobs executed on HADOOP cluster run as the end user as opposed to user "hive". For example, the HDFS permission checks during job executions will be against the end user.
