Default Ports

Fusion services run in their own JVM and listen for requests on a number of ports. Environment variables, set in a common configuration file, are used to specify the port a service uses. To change the port(s) a service uses, you must change the settings in the configuration file.

Default Ports

The default ports for the Fusion services are as follows:

Port	Service
8764	Fusion UI This service includes the Fusion Authorization Proxy
8765	Fusion API Services
8766	Spark Master
8769	Spark Worker
8984	Connectors Services
8983	Solr This is the embedded Solr instance included in the Fusion distribution.
9983	ZooKeeper The embedded ZooKeeper used by Fusion services. It corresponds to the ZooKeeper `clientPort` which is defined in file `fusion/3.1.x/conf/zookeeper/zoo.cfg`.
8766	Apache Spark master REST port
8767	Apache Spark master UI
8082 and 8770	Apache Spark worker UI
4040	Apache Spark driver UI
8769	Apache Spark worker listening port
7337	Shuffle port for Apache Spark worker
8600-8616	Akka ports used between Spark driver, master, workers and API See aka documentation
47100-48099	Apache Ignite TCP communication port range (used by API, Connectors and UI Proxy)
48100-48199	Apache Ignite shared memory port range (used by API, Connectors and UI Proxy)
49200-49299	Apache Ignite discovery port range (used by API, Connectors and UI Proxy)
51500-52000	Executor port, driver port, block manager port, file server port You will need to set these manually in config if needed. Otherwise you can ignore these.

Important

In a production environment, do not expose port 8765 to users. Using your firewall software or the Jetty configuration of the API server, make it accessible only to the auth proxy service and the connectors service.

Port settings are defined in the fusion.properties file.

Jetty is used to run Solr, the Fusion UI, API, and connectors services. For each of these services, Jetty runs the service on the assigned port and listens on a second port for shutdown requests. Therefore, fusion.properties defines pairs of ports for components running on Jetty, e.g.:

api.port = 8765
api.stopPort = 7765

ZooKeeper Port Configuration

The ZooKeeper ports are defined both in the fusion.properties file and in the zookeeper configuration file, zoo.cfg, in the zookeeper subdirectory, path fusion/3.1.x/conf/zookeeper/zoo.cfg.

The definition in

fusion.properties is:

zookeeper.port = 9983

The definition in zoo.cfg is:

clientPort=9983

Important

If you change the zookeeper port and are running the embedded zookeeper, the port definitions must match!
