Cellar discovery service

Hi all,

I had a very quick look at cellar discovery service and it looks great
however in Hazelcast 3.6 a new discovery SPI will be introduced and so far
there are a few implementation like etcd, dns, consul, kubernetes and some
other under development: would karaf-cellar adopt them in the future ?

Best regards,
Luca

Hi Achim,

well, I think there's almost nothing to do in Cellar except eventually drop
custom discovery-service and delegate it to hazelcast's built in ones as it
is only a matter of Hazelcast configuration.

But I'll open a Jira :-)

Hi Luca,

well, create a Jira for it, so it's not going to be forgotten ;)
Afaik we didn't have it on the road-map till now,
and maybe you're able to provide a pull-request for it :)

regards, Achim

Hi Luca,

see my comment in the Jira.

Even if Hazelcast Discover SPI is interesting, I would avoid to replace 
the Cellar Discovery service by Hazelcast one: even if Cellar uses 
Hazelcast, it's not tight to Hazelcast, and so, it could be used by 
different backends (zookeeper, yarn, mesos, whatever ...).

So using hazelcast discovery SPI will tight too much Cellar with 
Hazelcast. However, support Hazelcast Discovery SPI as a backend of 
Cellar Discovery can make sense.

Regards
JB
