Adding a New Search Node to the Configuration
Here's how to add a new Search node to your configuration:
- Take all Ingress Replicators out of the load balancer rotation.
- Wait for all Ingress Replicators to deliver pending activities. To do this, from the command line run: curl http://ingressReplicatorHostHere:PortHere/logging/metric/listCounters | grep InQueue
- This should return something like the following, which indicates that you are replicating to search1.foo.com:30000 and search2.foo.com:21000, and that the InQueue metric is 0.0, which means that all activities have been delivered: {"key":"counter>com.jivesoftware.service.activity.stream.replicator.ActivityStreamReplicator>search1.foo.com_30000>InQueue","metric":0.0}, {"key":"counter>com.jivesoftware.service.activity.stream.replicator.ActivityStreamReplicator>search2.foo.com_21000>InQueue","metric":0.0}
- Shut down the Ingress Replicators (service jive-ingress-replicator-service stop).
- Install the new Search Service 3.
- Copy the active Search index from Search Service 1 or 2 to the new Search Service 3. You can find the active search index by looking in /usr/local/jive/services/search-service/main-args.properties file for CONTENT_SEARCH_HOME_DIRECTORY=/path/to/dir. This property lists the location of the search indexes.
- Start Search Service 3 (service jive-search-service start).
- Next, you'll point the Ingress Replicators at the new Search node as described below.
Point to the New Search Node
After you've successfully added the new node as described above, you'll need the other nodes to point to the new Search Service node. Here's how to do that:
- In /usr/local/jive/services/ingress-replicator-service/, re-configure Ingress Replicator 1 and 2 to include Search Service 3. Set the load balancer to forward the ingress service to all machines holding the ingress replicator, and the ingress replicators to forward to all machines where the search service runs. The relevant parameters in the main-args.properties file should look something like this: PORT=29000 REPLICATE_INGRESS_TO_THESE_COMMA_SEPARATED_HOST_COLON_PORT_TUPLES=cs-d-hadoop02.eng.yourdomain.com:30000,cs-d-hadoop03.eng.yourdomain.com:30000
- Restart the Ingress Replicator services (service jive-ingress-replicator-service start).
- Add the Ingress Replicator services back into the load balancer configuration.
