> 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
