             Summary: Port winutils static code analysis change to trunk
                 Key: HADOOP-9443
                 URL: https://issues.apache.org/jira/browse/HADOOP-9443
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 3.0.0
            Reporter: Chuan Liu
            Assignee: Chuan Liu


We hit a problem in winutils when running tests on Windows. The static code analysis change will fix the problem. More specifically, the old code always assumes the security descriptor get from GetSecurityDescriptorControl() is relative, and will make an absolute security descriptor out of it. The new absolute security descriptor will then pass to SetSecurityDescriptorDacl() to set permissions on the file. If the security descriptor is absolute, the new absolute security descriptor will be NULL, and we will run into the problem. This is what happened exactly in our case. The fix from static code analysis will solve the problem.
