Review request for Ambari, Mahadev Konar and Robert Nettleton.
Bugs: AMBARI-10811
https://issues.apache.org/jira/browse/AMBARI-10811
Repository: ambari
Description
-------
When provisioning a cluster using a blueprint that contains HA components or an
existing MYSQL_SERVER or implicit MYSQL_SERVER (not explicitly specified in
blueprint but required by dependency) the cluster fails to deploy.
The request remains in the PENDING state and at 0% complete.
Output like the following is logged to ambari-server.out:
TopologyManager.ConfigureClusterTask: Entering
Caught an error from Config Processor: java.lang.IllegalArgumentException:
Unable to determine required host groups for component. Component
'MYSQL_SERVER' is not mapped to any host group or is mapped to multiple groups.
This is a regression as a result of
https://issues.apache.org/jira/browse/AMBARI-10750
The problem was that the blueprint config processor was not dealing with these
topologies properly when trying to determine which host groups needed to be
resolved prior to updating configuration.
