[jira] [Commented] (KARAF-4232) Kara Cellar discovery Vs Hazelcast discovery SPI

["Jean-Baptiste Onofré (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KARAF-4232?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15067042#comment-15067042 ] 

Jean-Baptiste Onofré commented on KARAF-4232:
---------------------------------------------

I'm not sure it's a good idea as it means that Cellar will be very tight coupled to Hazelcast. Even if it's not the case right now, cellar-core and cellar-hazelcast are decoupled, allowing you to use another implementation (for instance cellar-zookeeper, cellar-yarn, etc).

So I would avoid to only use hazelcast discovery SPI. However, it could make sense to provide a discovery service using the hazelcast one.

> Karaf Cellar has some built-in discovery mechanism that are great but  Hazelcast 3.6.0 is going to provide discovery SPIs and some implementations are already available:
> - https://hazelcast.atlassian.net/wiki/display/COM/HEP+2+-+Hazelcast+Discovery+SPI
> - http://hazelcast.org/plugins/
> - https://github.com/search?p=1&q=hazelcast-discovery&type=Repositories&utf8=%E2%9C%93
> Would Karaf Cellar eventually drop custom discovery plugin in favor native Hazelcast's ones ?
