Hi All, I have just started learning Apache Flink and found the guide link to start the development in EClipse IDE.
https://ci.apache.org/projects/flink/flink-docs-master/quickstart/java_api_quickstart.html When I RUN the WordCount.java file as Application it is throwing the below though i have scala-library 2.10.4 which contains the scala.collection,Traversable class in it. 00:20:26,993 INFO org.apache.flink.api.java.ExecutionEnvironment - The job has 0 registered types and 0 default Kryo serializers Exception in thread "main" java.lang.NoClassDefFoundError: scala/collection/Traversable at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:800) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:449) at java.net.URLClassLoader.access$100(URLClassLoader.java:71) at java.net.URLClassLoader$1.run(URLClassLoader.java:361) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) I'm not sure what I am missing over here. Please help out to overcome from this issue. -- Thanks and Regards Nyamath Ulla Khan
