Todd Lipcon created HADOOP-8410: ----------------------------------- Summary: SPNEGO filter should have better error messages when not fully configured Key: HADOOP-8410 URL: https://issues.apache.org/jira/browse/HADOOP-8410 Project: Hadoop Common Issue Type: Bug Components: security Affects Versions: 2.0.0 Reporter: Todd Lipcon Priority: Minor
I upgraded to a build which includes SPNEGO, but neglected to configure dfs.web.authentication.kerberos.principal. This resulted in the following error: 12/05/18 14:46:20 INFO server.KerberosAuthenticationHandler: Login using keytab //home/todd/confs/conf.pseudo.security//hdfs.keytab, for principal ${dfs.web.authentication.kerberos.principal} 12/05/18 14:46:20 WARN mortbay.log: failed SpnegoFilter: javax.servlet.ServletException: javax.security.auth.login.LoginException: Unable to obtain password from user Instead, it should give an error that the principal needs to be configured. Even better would be if we could default to HTTP/_HOST@<default realm> -- This message is automatically generated by JIRA.
