Hi jstar, I need to have a close look. But I am wondering why you use reflection in the first place? Is there any specific reason for that?
Furthermore, the example provided in project maven-example also covers the case to submit a topology to Flink via Java. Have a look at org.apache.flink.storm.wordcount.WordCountRemoteBySubmitter It contains a main() method and you can just run it as a regular Java program in your IDE. The SO question example should also work; it also contains a main() method, so you should be able to run it. Btw: If you use Storm-Compatiblitly-API there is no reason the get an ExecutuionEnvironment in you code. This happen automatically with FlinkClient/FlinkSubmitter. Furthermore, I would recommend to use FlinkSubmitter instead of FlinkClient as it is somewhat simpler to use. About SO question: I guess the problem is the jar assembling. The user says "Since I'using maven to handle my dependencies, I do a Mvn clean install to obtain the jar." I guess this is not sufficient to bundle a correct jar. Have a look into pom.xml from storm-examples. It uses maven plug-ins in assemble the jar correctly. (Regular maven artifact do not work for job submission...) Will have a close look and follow up... Hope this helps already. -Matthias On 04/13/2016 06:23 PM, star jlong wrote: > Thanks for the reply. > @Stephen, I try using RemoteEnvironment to submit my topology to flink. > Here is the try that I did RemoteEnvironment remote = new > RemoteEnvironment(ipJobManager, 6123, jarPath); remote.execute(); > While running the program, this is the exception that I got. > java.lang.RuntimeException: No data sinks have been created yet.
