             Summary: ZooKeeper Monitor for Knox Topology Config Changes
                 Key: KNOX-1012
                 URL: https://issues.apache.org/jira/browse/KNOX-1012
             Project: Apache Knox
          Issue Type: Sub-task
            Reporter: Phil Zampino


Knox should be able to monitor simple topology descriptors and provider 
configurations registered in ZooKeeper (per 
[KNOX-1010|http://issues.apache.org/jira/browse/KNOX-1006]), in order to notice 
when configurations have changed as compared with what has been deployed as a 
Knox topology.

* Simple descriptor changes
** Trigger re-generation/deployment of updated topology descriptor
** local (re-use existing FileAlterationMonitor?)
** remote
* Externalized provider config changes
** Trigger update of deployed topologies (runtime) that reference the modified 
provider config
** local (re-use existing FileAlterationMonitor?)
** remote
