> When *adding* Hive to an existing Kerberized cluster, the {{hive-site/hive.metastore.sasl.enabled}} value is set to {{false}} when it should be {{true}}.  If Hive was installed before enabling Kerberos,  
> {{hive-site/hive.metastore.sasl.enabled}} is set to {{true}} after enabling Kerberos.
> If {{hive-site/hive.metastore.sasl.enabled}} is {{false}} in a Kerberized cluster, the following error can be seen in the hiverserver2.log:
> {noformat:title=/var/log/hive/hiveserver2.log}

> *Cause*
> It appears that the front end is updating the Kerberos Descriptor _artifact_ with _old_ data rather than the data the is specified on the stack's Kerberos Descriptor. This occurs during the transition between the "Review" and "Install, Start, Test" pages of the "Add Service Wizard".
> *Solution*
> Use the current Kerberos Descriptor's values as default value for the updated Kerberos Descriptor and update only what the user changes in the relevant fields.
