---------------------------------------------------------------

Simple JAAS authentication like this will work, but I'm not sure it's a general 
solution even once the paths are made configurable and not hardcoded.  Could 
someone with more Kerberos comment on whether adding code like this to 
HiveMetaStoreBridge.java is the best approach?

------
System.setProperty("java.security.auth.login.config", "/jaas.conf");
System.setProperty("sun.security.jgss.debug", "true");
System.setProperty("javax.security.auth.useSubjectCredsOnly", "false");
System.setProperty("java.security.krb5.conf", "/etc/krb5.conf");

have a patch to review soon.

System.setProperty("sun.security.jgss.debug", "true");
System.setProperty("javax.security.auth.useSubjectCredsOnly", "false");
