> Currently, deploying a Blueprints cluster that includes the new LogSearch components does not have the appropriate amount of validation during the initial POST of the Blueprint.
> If a Blueprint is POST-ed to ambari-server with LogSearch components, but without a Zookeeper server instance ("ZOOKEEPER_SERVER"), the POST will succeed, but the Cluster deployment based on this Blueprint will eventually fail, as all LogSearch components require access to the cluster's Zookeeper quorum. 
> The stack definition metadata for the LogSearch service should be updated, so that the dependency on ZOOKEEPER_SERVER is explicitly required.  If a Blueprint includes LogSearch, but does not include the ZOOKEEPER_SERVER instance, this should result in an error thrown back to a cluster attempting to POST the invalid Blueprint. 
> While is is possible to deploy valid LogSearch clusters with Blueprints currently, this type of validation is required in order to assist the creation of new Blueprints, to ensure that the proper required components are included in the cluster. 
> I'm working on a fix for this, and will be submitting a patch shortly.
