    Description

      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)
      at java.security.AccessController.doPrivileged(Native Method)

      at org.apache.hadoop.security.authentication.server.AuthenticationFilter.init(AuthenticationFilter.java:148)
      ... 24 more

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