Symptoms

On BDA V4.2 when enabling AD Kerberos, the NameNode service will not come up.  The NameNode logs,  /var/log/hadoop-hdfs/hadoop-cmf-hdfs-NAMENODE-<host>.example.com.log.out,  show errors like:

2015-06-10 11:06:56,220 WARN org.apache.hadoop.security.UserGroupInformation:

This indicates that the NameNodes can not connect with the Journal Nodes when they start up, and so can not authenticate.
