[jira] [Created] (UIMA-4227) DUCCs Agent should call cgcreate when testing CGroups on startup

Jerry Cwiklik created UIMA-4227:
-----------------------------------

             Summary: DUCCs Agent should call cgcreate when testing CGroups on startup
                 Key: UIMA-4227
                 URL: https://issues.apache.org/jira/browse/UIMA-4227
             Project: UIMA
          Issue Type: Bug
          Components: DUCC
    Affects Versions: 1.1.0-Ducc
            Reporter: Jerry Cwiklik
            Assignee: Jerry Cwiklik
             Fix For: 2.0.0-Ducc


The agent currently tests for existence of cgroups folder on startup. If the folder doesnt exist, the agent just logs that fact and continues with cgroups disabled. This does not seem like a sufficient test. An older version of cgroups may be installed and the folder may exist but cgcreate can fail.
When checking for cgroups, call cgcreate to test if cgroups actually function correctly on a node. If this fail, the agent will continue on with cgroups disabled.
