Eric Yang created HADOOP-16094:
----------------------------------
Summary: AuthenticationFilter can trigger NullPointerException in KerberosName class
Key: HADOOP-16094
URL: https://issues.apache.org/jira/browse/HADOOP-16094
Project: Hadoop Common
Issue Type: Bug
Reporter: Eric Yang
Hadoop AuthenticationFilter example can fail with NullPointerException if auth_to_local rules has not been parsed from Configuration object. This can happen if the web application does not have any initialization code that leads to triggering: UserGroupInformation.initialize(conf, boolean);
