Yiqun Lin updated HDFS-10894:
-----------------------------
    Description: 
There two redundant charactors for command {{hdfs dfsadmin -saveNamespace}}. 
The introduction of this command in HDFSCommands.md

{code}
-saveNamespace \[-beforeShutdown\]  Save current namespace into storage 
directories and reset edits log....
{code}

Here the charactior '\' is no need, it makes this look incorrect. This is a 
link page for this document:
http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/HDFSCommands.html#dfsadmin
