[jira] [Created] (YARN-5472) WIN_MAX_PATH logic is off by one

Brook Zhou created YARN-5472:
--------------------------------

             Summary: WIN_MAX_PATH logic is off by one
                 Key: YARN-5472
                 URL: https://issues.apache.org/jira/browse/YARN-5472
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
         Environment: Windows
            Reporter: Brook Zhou
            Assignee: Brook Zhou
            Priority: Minor


The following check is incorrect:

    if (Shell.WINDOWS && sb.getWrapperScriptPath().toString().length() >     WIN_MAX_PATH)

should be >=, as the max path is defined as "D:\some 256-character path string<NUL>"
