> Noticed this while debugging issues in another application. We saw an error when trying
to do a FileSystem.get using an hftp file system on a secure cluster using a proxy user ugi.
> This is a small snippet used
> {code}
>  FileSystem testFS = ugi.doAs(new PrivilegedExceptionAction<FileSystem>() {
>             @Override
>             public FileSystem run() throws IOException {
>                 return FileSystem.get(hadoopConf);
>             }
>         });
> {code}
> The same code worked for hdfs and webhdfs but not for hftp when the ugi used was UserGroupInformation.createProxyUser
