Example 1 with AkkaRpcService

use of org.apache.flink.runtime.rpc.akka.AkkaRpcService in project flink by apache.

/**
	 * Utility method to create RPC service from configuration and hostname, port.
	 *
	 * @param hostname   The hostname/address that describes the TaskManager's data location.
	 * @param port           If true, the TaskManager will not initiate the TCP network stack.
	 * @param configuration                 The configuration for the TaskManager.
	 * @return   The rpc service which is used to start and connect to the TaskManager RpcEndpoint .
	 * @throws IOException      Thrown, if the actor system can not bind to the address
	 * @throws Exception      Thrown is some other error occurs while creating akka actor system
