> Provisioning multinode cluster using Blueprints fails as Ambari sends install and start
tasks only to a single node (agent) but not to nodes.
> Apparently this is being caused by an NPE thrown from 
> RecoveryConfigHelper.java: 146
> Long timestamp = hostTimestamp.get(hostname);
> if (timestamp.longValue() != recoveryTimestamp) {
>   return true;
> }
> for all agents except one. Due to the NPE the server never gets to execute the code that
adds the commands to be executed by the agent to the heartbeat response for the agent.
