>
> 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).
