> The Blueprint Configuration processor is not handling certain HA-specific properties (HDFS HA for one example) when host names are specified directly.
> If a customer wishes to specify hostnames directly in the HDFS HA properties that require hostnames, the Blueprint processor will fail if it detects more than one NameNode (which is the case in an HA cluster) and does not find the %HOSTGROUP% syntax to use for hostname substitution.
> The Blueprint config processor should be updated, so that customer-supplied hostnames in these properties are used, and the Blueprint processor should function properly with hostnames supplied directly.
> This fix should also be applied and tested across the other types of HA in Blueprints, and care should be taken to ensure that a customer can supply hostnames directly, or can use the %HOSTGROUP% syntax, or a combination of the two approaches.
