Hari Sekhon updated AMBARI-13907:
---------------------------------
Description:
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.
