[jira] [Commented] (AMBARI-24774) Wrong settings in exported blueprint

["Doroszlai, Attila (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AMBARI-24774?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16652087#comment-16652087 ] 

Doroszlai, Attila commented on AMBARI-24774:
--------------------------------------------

During cluster creation a service-level {{recovery_enabled: true}} setting in the blueprint results in _all_ components of that service not explicitly listed under {{"component_settings"}} to have "Auto Start" enabled.  Similarly, cluster-level {{recovery_enabled: true}} results in all components having "Auto Start" enabled.

Exported blueprints, however, have service/cluster-level {{recovery_enabled: true}} if _any_ component has "Auto Start" enabled.  This causes further discrepancy between original cluster and re-created cluster.

STR:

# Create ZooKeeper + Metrics cluster without any explicit recovery settings
   result: "Auto Start" is enabled only for Metrics Collector by default
# Export blueprint
# Create cluster using the exported blueprint
   result: "Auto Start" is enabled for every component

> Cluster blueprint export is broken wrt. the {{settings}} section.
> # Only one component per service is included.
> # Default setting value assumed to be {{false}}, ignoring component-level stack definition
> STR:
> # Disable "Auto Start" for Metrics Collector, for which it is enabled by default per stack definition
> # Enable "Auto Start" for both DataNode and NameNode
> # Export blueprint
> Result:

> Problem: creating a cluster using the exported blueprint results in different settings than the original cluster.  "Auto Start" would be disabled for DataNode and enabled for Metrics Collector per stack defaults.
