Beginning with EDR 7.8.0, UDP port 24884 is part of the Jolokia agent which is used with the datastore process and IPv6. This was added to enable IPv6 support in 7.8.0.
To disable the use of this port:
- Log into the server.
- Edit /etc/cb/datastore/datastore.in
- Append additional text at the end of the following line:
(original line)
DATASTORE_OPTS="${DATASTORE_OPTS} -javaagent:/usr/share/cb/datastore/bin/jolokia-jvm-agent.jar=port=${DatastoreMetricsPort},host=localhost"
(modified line)
DATASTORE_OPTS="${DATASTORE_OPTS} -javaagent:/usr/share/cb/datastore/bin/jolokia-jvm-agent.jar=port=${DatastoreMetricsPort},host=localhost,discoveryEnabled=false"
- Repeat this process for all nodes, primary and secondary servers.
- Restart the cluster.
