Hari Sekhon updated AMBARI-13907:
---------------------------------
Priority: Major (was: Critical)
> Ambari Blueprint provisioning error "list index out of range"
> -------------------------------------------------------------
>
> Key: AMBARI-13907
> URL: https://issues.apache.org/jira/browse/AMBARI-13907
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server, blueprints
> Affects Versions: 2.1.0
> Environment: HDP 2.3
> Reporter: Hari Sekhon
>
> When provisioning an Ambari cluster via a blueprint that was taken from an
> existing cluster install, Ambari fails with a list index out of range error
> on the metrics collector.
> I suspect this is due to not supplying all host_groups in the mapping json at
> cluster creation time but there was no validation on missing host groups to
> prevent this scenario so it fails late half way through the install.
