Subject Fwd: Exception in WordCount code.
Date Mon, 16 Oct 2017 14:24:02 GMT
Hi all,

I am new to Apache Flink and I followed http://training.data-
artisans.com/devEnvSetup.html
to start with Flink setup and sample code demo.

I am facing issue while running WordCount.java code in eclipse IDE.

I am getting " java.lang.NoClassDefFoundError:
org/jboss/netty/logging/InternalLoggerFactory"
exception.

Below is the console output -

19:35:33,364 INFO  org.apache.flink.api.java.ExecutionEnvironment
     - The job has 0 registered types and 0 default Kryo serializers
19:35:33,643 INFO  org.apache.flink.runtime.minicluster.FlinkMiniCluster
