> URL: https://issues.apache.org/jira/browse/AMBARI-7988
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 1.7.0
> Reporter: Robert Nettleton
> Assignee: Robert Nettleton
> Fix For: 1.7.0

> Attachments: AMBARI-7988.patch, AMBARI-7988_1.7.0.patch

> If a Blueprint is exported from a running cluster in Ambari, the following
> properties are not included in the exported Blueprint:
> yarn.timeline-service.address,
> yarn.timeline-service.webapp.address,
> yarn.timeline-service.webapp.https.address
> These properties are not included if the stack defaults are not overridden,
> which is likely a common case for the Yarn Timeline serivce.
> If these server properties are overridden with host name information prior to
> cluster start, then these properties do appear in the exported blueprint,
> with the relevant hostname information removed.
> The problem occurs when the defaults are used with this Yarn service. The
> service configuration defaults to "0.0.0.0", a special IP address used to
> indicate that a service listens on all network interfaces on a given machine.
> Since this address is slightly different than a normal host address, it must
> be handled differently by the Blueprint configuration processor.
> If the default "0.0.0.0" IP address is used for these defaults in the Yarn
> Timeline Service, the Blueprint configuration processor should allow these
> configuration properties to be included in the exported Blueprint.
> The current config processor will remove these properties, since no valid
> hostname is found during the export process.
> I'm working on a fix for this, and will be submitting a patch shortly.
