---------------------------------------------------------------------
Partial clustering is crucial in my opinion at least to share date between
author an public instance(s). Candidates are:
- public users (or users in general)
- comments or any other user generated content you like to see/maintain in the
author environment
Actually there are two 'similar' issues.
A) none clustered config triggers twice an installation
- this is what is described in the issue
B) clustered config does not trigger installation
- the mgnl-files are not extracted to the second instance: MAGNOLIA-1683
In general I think we cannot solve this for every scenario but for some of the
modules we might have some effort to do to make them cluster-able. Actually
those we think will be used in this kind of scenarios.

> Key: MAGNOLIA-2697
> URL: http://jira.magnolia-cms.com/browse/MAGNOLIA-2697
> Project: Magnolia
> Issue Type: Improvement
> Components: core, updatemechanism
> Affects Versions: 4.0.1
> Reporter: Jan Haderka
> Assignee: Philipp Bärfuss
>
> When creating partially clustered Magnolia instances, installation is
> cumbersome. In case of clustering "config" workspace only, other then first
> installed cluser node will assume installation was already done and will
> therefore not bootstrap content to other workspaces and not extract templates
> and other files to local FS either. In case of clustering any other
> workspace, installation will fail as soon as other then first installed node
> tries to install/bootstrap content into such workspaces (which was already
> filled while installing first cluster node) since it assumes installation was
> not yet performed.
> We need to think of mechanism how to configure the clustered instances or to
> make it easy to discover clustered workspaces and act during installation as
> appropriate.
> Current workaround is to in first case replicate necessary content for other
> workspaces and for FS manually and in second case to remove any offending
> bootstrap files from the module on other then fist cluster node prior to
> installing such a node.
