------------------------------------
Summary: Blueprint validation fails when dependency is deployed to
multiple host groups
Key: AMBARI-6135
URL: https://issues.apache.org/jira/browse/AMBARI-6135
Project: Ambari
Issue Type: Bug
Reporter: John Speidel
Assignee: John Speidel
Fix For: 1.6.1
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.
An example BP:

Attempting to register this blueprint results in:
{code}
{
"status" : 400,
"message" : "Cluster Topology validation failed. Unresolved component
dependencies: {host2={NIMBUS=[DependencyInfo[name=ZOOKEEPER/ZOOKEEPER_SERVER,
scope=cluster, auto-deploy=true]]}}. To disable topology validation and create
the blueprint, add the following to the end of the url:
'?validate_topology=false'"
}
