Hazelcast-Based Discovery Provider
A new ECF discovery provider has been created (September 15, 2019), based upon the Hazelcast communications library. See the Hazelcast website for technical specifics about Hazelcast and configuration and API documentation.
Getting Hazelcast Discovery Provider
The Hazelcast ECF Discovery provider repository is here.
A binary build of the Hazelcast Discovery Provider and Hazelcast Distribution Provider are available here.
Karaf Install
A Karaf features file karaf-features.xml (with both Distribution and Discovery features) is available in karaf-features.xml.
Hazelcast Discovery Provider Configuration Properties
The ECF Hazelcast Discovery Provider is configured via system properties. Here is a table of the Hazelcast Discovery Provider configuration system property properties and their default values:
| Property Name | Description | Type | Default value |
|---|---|---|---|
| ecf.discovery.hazelcast.configURL | Xml config file to config Discovery Hazelcast group. Example: file:///path//to/hazelcast.xml or http://host.com/path/to/hazelcast.xml | String | None - If not specified, uses file /hazelcast.xml file inside of bundle org.eclipse.ecf.discovery.provider.hazelcast, which uses Hazelcast multicast group: 224.2.2.5 and port: 54327. See here for entire default HC config file. |
| ecf.discovery.hazelcast.enabled | Flag to enable/disable Hazelcast Discovery via bundle org.eclipse.ecf.discovery.provider.hazelcast. True by default. Setting system property to anything other than 'true' will disable the ECF Hazelcast Discovery provider. | Boolean | true |
Note that these values and defaults are also defined in the source code in the org.eclipse.ecf.provider.internal.jms.hazelcast.Activator class available at githhub here.
