about starting the S4Node in for loop

[baojian Zhou]

when i started to  run the S4Node.class,  i have changed the main method to
a s4Node method and then invoke them 5 times. like this :

public static String[] commanderNode = new String[] { "-c", "cluster1" };
for (int i = 0; i < 5; i++) {
S4Node.s4Node(DeployFrameStream.commanderNode);
}

but it always stopped in the first invoke. And then i noticed:
signalOneAppLoaded.await();

how can i avoid this situation.
