The Definition of a class required by stream processing class is not found exception appears if a custom stream processing configuration is incorrect for a File data set.

Example message text

com.pega.bigdata.dataset.file.repository.streamprocessing.CustomStreamProcessingInvalidException:  

Problem with loading class definition com/pega/bigdata/dataset/file/repository/streamprocessing/sampleclases/ClassWithNoDefinition required by com.pega.bigdata.dataset.file.repository.streamprocessing.sampleclasses.CorrectStreamProcessin

Caused by: java.lang.ClassNotFoundException: com.pega.bigdata.dataset.file.repository.streamprocessing.sampleclasses.ClassWithNoDefinition

Next Steps

Verify that the class that you implemented for custom stream processing has no dependencies on third-party libraries. If these libraries are required to use your class, upload the missing .jar files to the system classpath.
