Do I need to configure a port for Spark Engine Monitoring?
Spark engine monitoring requires the cluster nodes to communicate with the Data Integration Service over a socket. The Data Integration Service picks the socket port randomly from the port range configured for the domain. The network administrators must ensure that the port range is accessible from the cluster nodes to the Data Integration Service. If the administrators cannot provide a port range access, you can configure the Data Integration Service to use a fixed port with the SparkMonitoringPort custom property. The network administrator must ensure that the configured port is accessible from the cluster nodes to the Data Integration Service.
