Hi Fernando,
I'm not sure I follow you.
In Cellar, if sync is enabled, at startup, a Synchronizer is called.
The synchronizer:
1/ gets the resources (bundles for instance) from the cluster, compare
the state on the cluster with the state on the node, and update the
state on the node.
2/ push the local resources states to the bundles.
You have a synchronizer for bundle, one for features, one for config, etc.
After that that, Cellar have a set of listener that listen for local
events (bundle install, features install, etc) and broadcast this local
event as cluster event.
You have a listener for bundle, one for features, one for config, etc.
Bundles and features are completely isolated: if you blacklist all
bundles, you can still install features on the cluster, the bundles list
will remain empty.
Could you share (directly with me in private e-mail) your scenario ?
Regards
JB

I'd think that the list to change is that of the first node, which
shouldn't be unexpectedly empty after the feature is installed. Regards.

Hi Jean-Baptiste,
I have successfully completed an installation of the web console in a
shared instance and cluster group blacklisting the webconsole feature and
disabling bundle sync (as advised) in both nodes.
Regarding the bundle lists, I have verified that the list in the other
nodes is different than the empty list in the node where the feature is
installed (when bundle sync is enabled, of course), can you double check if
that is the expected behavior?

Humm, I guess the blacklists/whitelists are the same, but I will check
again and get back to you. Regards.

Not necessary: cluster:bundle-list should be the same, bundle:list
depends of the blacklist/whitelist.

Allright, but the list should be the same in the two nodes, right?

Hi Fernando,
If you blacklist the webconsole feature, Cellar will block the
feature:install and cluster:feature-install webconsole events.
If you install locally feature:install and use bundle sync, the
bundles will be sync. It's normal.
By default, I disable the bundle sync (blacklist=* whitelist=none
for the bundles).

Hi Jean-Baptiste,
I am still thinking if the replication of the bundles to the
second node
is really an issue, and also that the fact that the bundle list
in the
two nodes isn't the same should be reported separately.
Let me know when you find the time to look into this with me.

Hi Jean-Baptiste,
I am getting an exception from Jetty when following these
steps:
1- Create node1
2- Install Cellar on node1
3- Edit org.apache.karaf.cellar.__groups.cfg to blacklist
the
webconsole feature
4- Create node2
5- Install Cellar on node2
The reason why I did mentioned "a list" in my previous
e-mail is
because I understand the issue could be worked around
blacklisting
the Jetty bundles, for example.
The log files are attached for your review, as well as the
list of
bundles in node2, which is very different than the empty
list in node1.
Please advise me whether I should open a ticket.

Hi Jean-Baptiste,
I have the impression that you actually need to
blacklist some
bundles as well, will re-do the installation and come
back with
more detailed information.

Hi Fernando,
you mean install the WebConsole only on one node ?
If so, you can blacklist webconsole feature
inbound and
outbound and install on the target node.

All,
After some investigation, I've managed to
install the
web console in a
Cellar installation using a dedicated instance
in a
different cluster group.
I understand that I could use a shared instance
in a
single cluster
group if I blacklisted some features and
bundles, but
don't have that
list yet - do you?
