> Key: AMBARI-6135
> URL: https://issues.apache.org/jira/browse/AMBARI-6135
> Project: Ambari
> Issue Type: Bug
> Reporter: John Speidel
> Assignee: John Speidel
> Labels: blueprints
> Fix For: 1.6.1
>
> Original Estimate: 1h
> Remaining Estimate: 1h

> When a component has a specified dependency and the number of instances of the component in the blueprint > 1, validation fails. An example of this is multiple ZK server instances and any component such as Nimbus being deployed which have a dependency on ZOOKEEPER_SERVER. Because there are 3 ZK server instances, the dependency should be satisfied but validation fails.
