[jira] Created: (HADOOP-6823) Provide validation of security-related settings on startup

Provide validation of security-related settings on startup
----------------------------------------------------------

                 Key: HADOOP-6823
                 URL: https://issues.apache.org/jira/browse/HADOOP-6823
             Project: Hadoop Common
          Issue Type: Improvement
    Affects Versions: 0.22.0
            Reporter: Jakob Homan
            Priority: Minor


There are several new config settings for security, involving keytab files, kerberos principals, security filters, etc. that need to be set for a secure cluster to come up.  It'd be nice if on startup, we checked that the required config values have been set and have something vaguely reasonable for values.  Displaying this information as well would provide a good summary for those trying to debug cluster security issues.
