Ted Malaska commented on HADOOP-8787: ------------------------------------- Thank you Todd, I didn't see that. I will get an updated patch soon. Also after reviewing the init method in AuthenticationFilter, I have a question about line 154 Line 154 looks like it will never return the config value for SIGNATURE_SECRET. Because it follows line 129. 129 Properties config = getConfiguration(configPrefix, filterConfig); 154 String signatureSecret = config.getProperty(configPrefix + SIGNATURE_SECRET); I'm going to make a test to check to see if signature secret is getting populated in the case of a prefix. > KerberosAuthenticationHandler should include missing property names in > configuration > ------------------------------------------------------------------------------------ > > Key: HADOOP-8787 > URL: https://issues.apache.org/jira/browse/HADOOP-8787 > Project: Hadoop Common > Issue Type: Improvement > Components: security > Affects Versions: 1.0.3, 3.0.0, 2.0.1-alpha > Reporter: Todd Lipcon > Assignee: Ted Malaska > Priority: Minor > Labels: newbie > Attachments: HADOOP-8787-0.patch, HADOOP-8787-1.patch > > > Currently, if the spnego keytab is missing from the configuration, the user > gets an error like: "javax.servlet.ServletException: Principal not defined in > configuration".
