> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.4.0
> Reporter: Nahappan Somasundaram
> Assignee: Nahappan Somasundaram

> Fix For: 2.4.0

>
> 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.
