Robert Levas updated AMBARI-9666:
---------------------------------
    Attachment: AMBARI-9666_01.patch

* Added code to inject Kerberos-related stages when added components move from INIT to INSTALLED
state
* Remove code that places stages in incorrect order in workflow
* Added ability to handle when hosts are removed, removing database entries for principals
on that host
* Changed when the auth_to_local map is built
* Handled adding hosts and adding services after Kerberos is enabled for the cluster

> When adding a service to a _Kerberized_ cluster, the {{INSTALL}} stage for that service
tends to fail due to missing Kerberos properties, principals and keytabs. 
> To solve this issue, when a new service is added to a _Kerberized_ cluster the following
needs to occur before that service can attempt to transition into it's {{STARTED}} state:
> # Kerberos-specific properties need to be created or set
> # Principals need to be created
> # Keytab files need to be generated
> # Keytab files need to be distributed
