KNOX-2689 - Redeploying a topology only if it was actually changed (#518)
> Avoid redeploying an unchanged topology
> ---------------------------------------
>
> Key: KNOX-2689
> URL: https://issues.apache.org/jira/browse/KNOX-2689
> Project: Apache Knox
> Issue Type: Improvement
> Affects Versions: 1.0.0, 1.1.0, 1.2.0, 1.3.0, 1.4.0, 1.5.0, 1.6.0
> Reporter: Sandor Molnar
> Assignee: Sandor Molnar
> Priority: Major
> Fix For: 2.0.0
>
> Time Spent: 1.5h
> Remaining Estimate: 0h
>
> Currently, if a topology is built from a provider/descriptor pair, Knox
> checks the content of the "new" topology upon "onFileChange" (\{{touch
> descriptor}}) and does not generate the topology if it's the same as the
> currently deployed topology.
> This check is not implemented on the old-style XML-based topology handling
> path.
> Note: as a side effect, touching a topology file will no longer trigger the
> topology redeployment.
