> When attempting to restart the HDFS NameNode after running the Kerberos
> wizard to enable Kerberos, the NameNode fails to startup.
> The underlying failure in the ambari-agent appears to be:
> "Traceback (most recent call last):
> File
> "/var/lib/ambari-agent/cache/common-services/HDFS/2.1.0.2.0/package/scripts/namenode.py",
> line 298, in <module>
> NameNode().execute()
> File
> "/usr/lib/python2.6/site-packages/resource_management/libraries/script/script.py",
> line 214, in execute
> method(env)

> line 194, in hdfs_repo_properties
> config_dict['dfs.datanode.kerberos.principal'] = params._dn_principal_name
> AttributeError: 'module' object has no attribute '_dn_principal_name'"
> This keeps the HDFS NameNode from starting up properly after Kerberos is
> Enabled, and this seems to keep the process of Enabling Kerberos from
> completing.
> The problem appears to be a Python coding issue where _private_ variables
> (declared with a leading underscore) are not imported from
> {{common-services/HDFS/2.1.0.2.0/package/scripts/params_linux.py}} into
> {{common-services/HDFS/2.1.0.2.0/package/scripts/setup_ranger_hdfs.py}}.
