Subject Re: [gelly] Tests fail, but build succeeds
Date Tue, 10 Mar 2015 16:36:36 GMT
So the sysout suppression worked like a charm. Thanks!

However, this mini cluster setup is giving me a bit of a rough time.
I added this to the test suite:

@BeforeClass
public static void setupCluster() {
   Configuration config = new Configuration();
   config.setInteger(ConfigConstants.LOCAL_INSTANCE_MANAGER_NUMBER_TASK_MANAGER,
2);
   config.setInteger(ConfigConstants.TASK_MANAGER_NUM_TASK_SLOTS, 2);
   config.setString(ConfigConstants.AKKA_WATCH_HEARTBEAT_PAUSE, "2 s");

   cluster = new ForkableFlinkMiniCluster(config, false);
}

And then I got:
org.jboss.netty.channel.ChannelException: Failed to bind to: /127.0.0.1:6123

because the address was already in use.

Also, do I have to use something like this
ExecutionEnvironment.createRemoteEnvironment(
                        "localhost", cluster.getJobManagerRPCPort());
instead of getExecutionEnvironment()?

I get the same error in both cases.

Thank you!
Andra
