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

Which revision is the patch against? Since no such method "public boolean commit() throws LoginException" found in http://svn.apache.org/repos/asf/hadoop/common/branches/branch-0.20/src/core/org/apache/hadoop/security/UserGroupInformation.java.

> user object in the subject in UGI  should be reused in case of a relogin.

>  In case of a relogin, a new user object is created in the subject. This causes the subject to lose some state for example authentication method. Instead, a new user object should not be added to the subject if one is already present.
