> The authentication mechanism for http specified via _hadoop.http.authentication.type_
is matched in in a case sensitive way. If one specifies the type {simple,kerberos}  in the
wrong case, the following exception is thrown . 
> Caused by: java.lang.ClassNotFoundException: Simple
> 	at java.net.URLClassLoader$1.run(URLClassLoader.java:366)
> 	at java.net.URLClassLoader$1.run(URLClassLoader.java:355)

> 	... 24 more
> I believe , it is safe to ignore case during this comparison.
