Error with zookeeper & storm

问题

I am developing a code for Storm, which is an example of the developers. My problem is that when you run this code from IDE Eclipse, do not get the connection between Storm and Zookeeper is established. Zookeeper is running in 2181 and is also set in storm.yaml.

My exception is:

72992 [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2000] WARN  o.a.s.s.o.a.z.s.NIOServerCnxn - caught end of stream exception

Any idea or procedure to be performed? Pass from the configuration code? And as I do?

回答1:

I faced the same issue in the past,when I was beggining with Storm. I'm not an expert yet, but I can afford to say that @Matthias J. Sax is right, the topology must run in local-mode to start it on Eclipse. I did that with Eclipse Mars, running Storm 0.10.0 and worked perfect. You have to do this:

Replace:

StormSubmitter.submitTopology("test", conf, builder.createTopology());

With:

 LocalCluster cluster = new LocalCluster();
      cluster.submitTopology("test", conf, builder.createTopology());

Hope it helped you.
