Hi Tam, In the install documentation, http://uima.apache.org/d/uima-ducc-1.0.0/installation.html, the section "Multi-User Installation and Verification" describes how to configure setuid-root for ducc_ling so that DUCC jobs are run as the submitting user instead of user "ducc".
The setuid-root ducc_ling should be put on every DUCC node, in the same place, and ducc.properties updated to point at that location.
