Remotable services with etcd discovery problem

[Tomáš Fecko]

Hi,

we are testing the etcd discovery, instead of jgroups...

There is one etcd instance on machine, and multiple fabric3 nodes - so only localhost communication.

It doesn't look like the nodes in single domain, in different zones, knows about each other:

I can see logs on nodeExecutors1 in libradeExecutors:node:zoneExecutors1:

[INFO 02.11.2015 17:28:04.903] Fabric3 ready [Name: libradeExecutors:node:zoneExecutors1:nodeExecutors1, Domain: libradeExecutors, Zone: zoneExecutors1, Mode:NODE, Environment: executors]

and I can see logs on nodeExecutors2 in libradeExecutors:node:zoneExecutors2:

[INFO 02.11.2015 17:28:10.587] Fabric3 ready [Name: libradeExecutors:node:zoneExecutors2:nodeExecutors2, Domain: libradeExecutors, Zone: zoneExecutors2, Mode:NODE, Environment: executors]

but there is no log, that would describe that they know about each other, like it was in the past...

Presence of logs in not the problem though. 

When I deploy composites, which were working on jgroups discovery based domain, they are not working now:

Hi Tomas,

This looks like a problem in the extension. Let me take a look today or tomorrow...
