             Summary: UIMA-DUCC: Agent truncates user names when collecting node processes
                 Key: UIMA-5744
                 URL: https://issues.apache.org/jira/browse/UIMA-5744
             Project: UIMA
          Issue Type: Bug
          Components: DUCC
            Reporter: Jerry Cwiklik
            Assignee: Jerry Cwiklik
             Fix For: 2.2.2-Ducc


When collecting user processes running on a node, an agent uses a command similar to this:

ProcessBuilder pb = new ProcessBuilder("ps", "-Ao",
 "user,pid,ppid,args,stat", "--no-heading");

When the above is run, linux truncates the user name to 10 characters. This effects code in the following classes:

CGroupsManager.java, NodeMemInfoCollector.java, NodeUsersCollector.java

Modify the command to use: user:32.
