In future releases, it may be possible to auto-generate some of this configuration, in order to ease the burden of HA setup for the Blueprints/Ambari user. > This work will involve changes to the Blueprint validation code, since our stacks do not currently support HA directly. It should be possible to deploy a NameNode HA Blueprint without turning off Blueprint validation. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
