Hi Daniel, Yes, it is possible to use UserGroupInformation#createProxyUser in an unsecured (simple authentication) cluster. You'll still need to specify in configuration which users can do impersonation, which originating hosts those users may perform impersonation from, and which groups of other users they may impersonate. This configuration is documented here:
http://hadoop.apache.org/docs/r2.7.1/hadoop-project-dist/hadoop-common/Supe rusers.html Other projects in the Hadoop ecosystem, such as Oozie, may have additional configuration requirements to support proxy users. Please see the documentation for those projects if needed. I hope this helps. --Chris Nauroth On 9/3/15, 10:27 AM, "Daniel Schulz" <danielschulz2...@hotmail.com> wrote: >Hi, > >When I run my Hadoop with simple authentication without a Kerberos: will >I be able to createProxyUser / doAs in order to make a superuser act upon >a less privileged user?
