Hmmm that's interesting but at least we move forward :)
I think because you added the following without adding these keys in the
properties files, it throws the execption:
@Override
public Collection<String> getLoadProfileEstimatorConfigurationKeys() {
return Arrays.asList("wayang.java.kafkatopicsource.load.prepare",
"wayang.java.kafkatopicsource.load.main");
}
Maybe try to add a cost function in the java properties file for the
kafkatopisource:
https://github.com/apache/incubator-wayang/blob/cd4936e665c2978394943117b44853f7ebabbec8/wayang-platforms/wayang-java/src/main/resources/wayang-java-defaults.properties
You can copy the one of the collectionsource for now.
To also check it quickly you could also try to not overload the
getLoadProfileEstimatorConfigurationKeys() method.
