    Description

      If the first call to UGI is UGI.setConfiguration(conf), it will try to initialize UGI class. During this initialization, the code calls KerberosName.setConfiguration(). KerberosName's static initializer will in turn call UGI.isSecurityEnabled(). Since UGI hasn't been completely initialized yet, isSecurityEnabled() will re-initialize UGI with a DEFAULT conf. As a result, the original conf used in UGI.setConfiguration(conf) will be overwritten by the DEFAULT conf.
