Bugs: AMBARI-12356
https://issues.apache.org/jira/browse/AMBARI-12356
Repository: ambari
Description
-------
STR:
1. Install old version of ambari (2.0.1)
2. Enable security

Expected results:
Can start all added components.
# Cause
The Kerberos Descriptor structure changed between Ambari 2.0 and Ambari 2.1.
This change moved the "hdfs" Kerberos identity descriptor from the _global_
scope to under the HDFS service. After upgrading from Ambari 2.0 to Ambari 2.1
an additional "hdfs" Kerberos identity descriptor was added with the new
principal name pattern - ${hadoop-env/hdfs_user}-${cluster_name}@${realm}.
This occurred because the stored Kerberos Descriptor contained the _old_
structure, and when Ambari generated a composite Kerberos Descriptor made up of
the Kerberos Descriptor compiled from the relevant stack definition with stored
changes applied, that additional "hdfs" Kerberos identity descriptor was added.
Because if this, the Kerberos logic became _confused_ and overwrote the
existing hdfs keytab file with one that contained the new principal name.
# Solution
While migrating Ambari 2.0 to Ambari 2.1, fix the stored Kerberos Descriptor
structure to match the new version's structure.
