--------------------------------------------
> 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
> Priority: Major
>
> 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.
