             Summary: Skip re-deployment of generated topology if the topology 
has not changed
                 Key: KNOX-2302
                 URL: https://issues.apache.org/jira/browse/KNOX-2302
             Project: Apache Knox
          Issue Type: Improvement
          Components: Server
    Affects Versions: 1.4.0
            Reporter: Philip Zampino
            Assignee: Philip Zampino


Knox discovery +always+ writes generated topologies to disk, triggering 
[re]deployment of that topology. It would be better to compare the generated 
topology against the already-deployed version (if it exists) prior to writing 
it to disk. If the generated version is the same as the already-deployed 
version, then the newly-generated topology should be discarded, so the 
re-deployment will be skipped.
