This would have the benefit of being able to > choose this option on a per-cluster basis, and not require an ambari-server > restart if this feature is desired but not enabled by default. > The following code reference shows how the "provision_action" configuration > option is used by a Blueprints deployment: > org.apache.ambari.server.topology.HostRequest#createTasks -- This message was sent by Atlassian JIRA (v6.3.4#6332)
