This is the service discovery system for the ness computing platform. It generally is deployed as a Galaxy tarball and provides service discovery for the rest of the platform.
In galaxy, a three level (environment, deployment, service) configuration is used. The environment configuration is used to locate all the discovery servers and configure platform wide defaults.
For development, a single discovery server can be used.
ness.zookeeper.clientPort=21052
ness.zookeeper.clientPortAddress=127.0.0.1
#
ness.zookeeper.server.1=127.0.0.1:21050:21051
#
# Discovery Service
#
ness.discovery.enabled=true
ness.discovery.root=/ness/srvc/development
ness.discovery.scan-interval=120s
ness.discovery.tick-interval=100ms
ness.discovery.zookeeper-timeout=500ms
ness.discovery.penalty-time=600s
For a real environment, at least three servers should be present.
