Subject [jira] [Created] (HADOOP-10665) Make Hadoop Authentication Handler loads case in-sensitive
Date Thu, 05 Jun 2014 19:41:03 GMT
Benoy Antony created HADOOP-10665:

             Summary: Make Hadoop Authentication Handler loads case in-sensitive
                 Key: HADOOP-10665
                 URL: https://issues.apache.org/jira/browse/HADOOP-10665
             Project: Hadoop Common
          Issue Type: Improvement
          Components: security
            Reporter: Benoy Antony
            Assignee: Benoy Antony
            Priority: Minor

The authentication mechanism for http specified via _hadoop.http.authentication.type_ is matched
in in a case sensitive way. If one specifies the type {simpe,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$1.run(URLClassLoader.java:355)
	at java.security.AccessController.doPrivileged(Native Method)
	at java.net.URLClassLoader.findClass(URLClassLoader.java:354)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:425)
	at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:358)
	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.
