Hi, first of all, am I correct to assume that new SocketSource(hostName1, port, '\n', -1) should be new SocketTextStreamFunction(hostName1, port1, '\n', -1)
or are you using a custom built SocketSource for this? If I replace it by SocketTextStreamFunction and execute it the example runs and prints incoming Strings from both input sockets. How are you executing the example? In the IDE or on a Flink cluster?
