Nihal Jain updated HBASE-20715:
-------------------------------
    Description: 
I have a habit of setting "Content-Type: text/xml" for curl commands. Today, I 
had a bad time debugging the 400 error for below command. Finally, this 
discussion(https://issues.apache.org/jira/browse/HBASE-14147?focusedCommentId=15205420&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15205420)
 helped me in resolving the problem.

As pointed out by [~mwarhaftig] and [~misty] in their discussion in 
HBASE-14147, a curl request of the following form will throw a {{400 BAD 
REQUEST}}
{code:java}
curl -vi -X POST -H "Accept: text/xml" -H "Content-Type: text/xml"  
"http://my_server:20550/namespaces/new_ns2/";
{code}
I think we should document this in the description for "Create a new namespace" 
explicitly mentioning that users should take care "Content-Type" is not set for 
this particular command. Similarly for "Alter an existing namespace" command.
 * *With {{"Content-Type: text/xml":}}* INCORRECT

{code:java}
curl -vi --negotiate -u:test -X POST -H "Accept: text/xml" -H "Content-Type: 
text/xml" http://host-xx-xx-xx-xx:xxxx/namespaces/testspace123
{code}
** Output:
{noformat}
