             Summary: Blueprints: Support for Blueprint export of a running Kerberized Cluster
                 Key: AMBARI-13712
                 URL: https://issues.apache.org/jira/browse/AMBARI-13712
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
            Reporter: Sandor Magyari


This task involves implementing the support for exporting a Blueprint from a Kerberized cluster, and having this document contain everything necessary to re-create this Kerberized cluster with new hardware.
An exported Blueprint for a Kerberized cluster will need to contain:
The existing component and configuration for the cluster (this can remain as it currently is, no changes required)
The “kerberos-env” and “k2b5-conf” configuration types. This will largely occur automatically, since these types are just plain configuration types on the cluster, and will be exported along with the other config types. Note: There will be some work required here in order to make sure that hostnames and passwords are not included in the exported Blueprint. The BlueprintConfigurationProcessor will need to be updated to properly mask out the hostnames/passwords. This is similar to existing config type handling, and will be a relatively small amount of work.
The Kerberos state of the cluster. The Blueprint processor will need to query the “KerberosHelper” API to determine if a cluster is Kerberized. If Kerberos is enabled, then the Blueprint processor will use the same API to obtain the Kerberos descriptor associated with this cluster (found as a REST resource under /api/v1/clusters/cluster_name/artifacts/kerberos_descriptor). This Kerberos descriptor should be added to the exported Blueprint, as an embedded descriptor inside the Blueprint .json file.
We should be able to export a Blueprint from a Kerberized cluster regardless of the initial deployment type (Ambari UI used to create cluster vs. Blueprint deployment used to create cluster).
