-----------------------------------

             Summary: Ducc's Agent should add cpu control group for processes it spawns 
                 Key: UIMA-4259
                 URL: https://issues.apache.org/jira/browse/UIMA-4259
             Project: UIMA
          Issue Type: Bug
          Components: DUCC
            Reporter: Jerry Cwiklik
            Assignee: Jerry Cwiklik
             Fix For: 2.0.0-Ducc


Ducc's agent currently assigns only memory control for a process launched into a CGroup container to enforce fair share use of memory. Extend this by adding a cpu control to make sure a single process (and its children) doesn't take more cpu than its fair share. Cgroups will allow a single process to use 100% of its CPU, but when another is started the cpu control group will reduce the allotment to 50%.
