Description

OfflineImageViewer is renewed to handle the new format of fsimage by HDFS-5698 (fsimage in protobuf).

We should document the followings:

• The tool can handle the layout version of Hadoop 2.4 and up. (If you want to handle the older version, you can use OfflineImageViewer of Hadoop 2.3)
• Delimited, Indented, and Ls processor were removed.
• A new Web processor, which supersedes the Ls processor, was added.
