FsImage offline viewer

I have fsimage stored in my local directory, Using offline viewer command specified at 'https://archive.cloudera.com/cdh/3/hadoop/hdfs_imageviewer.html' I have followed the instruction and executed the below command : hadoop oiv -i fsimage -o fsimage.txt Output is :

16/06/24 08:09:18 INFO offlineImageViewer.FSImageHandler: Loading 24 strings
16/06/24 08:09:18 INFO offlineImageViewer.FSImageHandler: Loading 3027842 inodes.
16/06/24 08:09:32 INFO offlineImageViewer.FSImageHandler: Loading inode references
16/06/24 08:09:32 INFO offlineImageViewer.FSImageHandler: Loaded 0 inode references
16/06/24 08:09:32 INFO offlineImageViewer.FSImageHandler: Loading inode directory section
16/06/24 08:09:35 INFO offlineImageViewer.FSImageHandler: Loaded 1446245 directories
16/06/24 08:09:35 INFO offlineImageViewer.WebImageViewer: WebImageViewer started. Listening on /127.0.0.1:5978. Press Ctrl+C to stop the viewer.

But the fsimage.txt file is of zero size, I have executed the command for XML format

hdfs oiv -p XML -i fsimage -o fsimage.xml

Which gives me fsimage.xml but I want this to be in '.txt' format, also In the output it says :

WebImageViewer started. Listening on /127.0.0.1:5978. Press Ctrl+C to stop the viewer.

Is there any UI available for accessing it, if yes how can we access it?

You can use indented format which is delineate the section of fsImage into separate levels of indentation.This also will be saved in txt format
