> In UserGroupInformation::doAs(), it prints out a log at ERROR level whenever 
> it catches an exception.
> However, it prints benign warnings in the following paradigm:
> {noformat}
>  try {
>         ugi.doAs(new PrivilegedExceptionAction<FileStatus>() {
>           @Override
>           public FileStatus run() throws Exception {
>             return fs.getFileStatus(nonExist);
>           }
>         });
>       } catch (FileNotFoundException e) {
>       }
> {noformat}
> For example, FileSystem#exists() follows this paradigm. Distcp uses this 
> paradigm too. The exception is expected therefore there should be no ERROR 
> logs printed in the namenode logs.
> Currently, the user quickly finds out that the namenode log is quickly filled 
> by _benign_ ERROR logs when he or she runs distcp in secure set up. This 
> behavior confuses the operators.
> This jira proposes to move the log to DEBUG level.
