Hadoop multi-user security

The regular behavior of DSS is to run as a single UNIX account on its host machine (let’s call it dssuser). When a DSS end-user executes an Hadoop recipe or notebook, it runs on the cluster as the dssuser Hadoop user.

DSS supports an alternate mode of deployment, called multi-user security. In this mode, DSS will impersonate the end-user and run all user-controlled code under a different identity than the dssuser user.
