Calling: java -cp ../examples/flink-java-examples-0.9-SNAPSHOT-KMeans.jar org.apache.flink.examples.java.clustering.util.KMeansDataGenerator 500 10 0.08
Will not connect to Flink. Its just running a standalone KMeans data generator, not KMeans. I would suspect that the KMeans example is not running as well. You can run the KMeans example like this: bin/flink run ./examples/flink-java-examples-0.9-SNAPSHOT-KMeans.jar.
