just curious what causes this class special? Need explicit load. |
this class is used by jetcd client internally to start a grpc channel, and for some reason native couldn't find it unless a explicit call to say JNIEnv->FindClass() is made, I've tried doing ClassLoader at AlluxioFuse side to just load the class, but still it couldn't find in native. One another way is to create an instance of this class at time of starting AlluxioFuse, but I thought its not extendable if there's other places using native lib, but as we are explicitly checking in .dylib and .so lib let me try if I can load the class at process startup time. |
