Ambari blueprint export doesn't respect the host_group name provided

[#1]

Versions:
HDP 2.6.4.0-91
Ambari 2.6.1

I have deployed a cluster using blueprints, with custom host_groups names (like hdp-masternode-01, hdp-worker ..)
then successfully added a new worker using host_group 'hdp-worker' specified in my blueprint.

From this state i downloaded the cluster blueprint, in which, the host_groups have changed to: 'host_group_1' 'host_group_2'...

Is there any know bug about that ?

Thanks

This is not a bug, rather an expected current design.

When we export a blueprint from a cluster then its a fresh blueprint of the current state of that cluster and the host_group names are just template names like host_group_1 / host_group_2 . Those are just placeholder variable names.
