Hi, I’m thinking I’m doing something wrong. After setting jobManager address to 127.0.0.1, I can run kmeans example (java -cp ../examples/flink-java-examples-0.9-SNAPSHOT-KMeans.jar org.apache.flink.examples.java.clustering.util.KMeansDataGenerator 500 10 0.08) But I can’t run word count example (bin/flink run ./examples/flink-java-examples-0.9-SNAPSHOT-WordCount.jar file:'///Users/Vidura/Documents/Development/flink/flink-dist/target/flink-0.9-SNAPSHOT-bin/flink-0.9-SNAPSHOT/hamlet.txt' file:'///Users/Vidura/Documents/Development/flink/flink-dist/target/flink-0.9-SNAPSHOT-bin/flink-0.9-SNAPSHOT/count.txt’)
