Here is the strange behavior.
Below code works in one box but not in the other. I had it working in my laptop the whole of yesterday, but strangely today it doesnt work in my desktop.
Can anyone please let me know what the issue is.
public static void main(String[] args) throws Exception {
try {
final StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
DataStream<String> msgDataStream1 = env.addSource((new SocketSource(hostName1, port, '\n', -1))).filter(new MessageFilter()).setParallelism(1);
DataStream<String> msgDataStream2 = env.addSource((new SocketSource(hostName2, port, '\n', -1))).filter(new MessageFilter()).setParallelism(1);
env.execute("Stock stream");
} catch (Exception e) {
System.err.println("Exception = > " + e.getMessage());
e.printStackTrace();
}
}
private static void unionMessageStreams(DataStream<String> msgDataStream1, DataStream<String> msgDataStream2) {
try {
DataStream<String> ds = msgDataStream1.union(msgDataStream2);
ds.print();
} catch (Exception e) {
System.err.println("Exception in union Message Streams () = > " + e.getMessage());
}
}
