edu.iu.dsc.tws.local.util.LocalClassLoader

public class LocalClassLoader
extends java.security.SecureClassLoader

This class loader will be used to virtually create isolated contexts for Worker instances. This will,

• Exclude all classes in java. or sun. packages
• Exclude Twister2Job, Config and Config.Builder, since they should be passed from parent loader to this loader
• Exclude edu.iu.dsc.tws.proto package, since it has lot of inner classes and not much useful for the local runner
