I'm a newbee in Spark. I know that what the work should do is written in RDD. But I want to make the worker load a native lib and I can do something to change the content of the lib in memory. So how can I do. I can do it on driver, but not worker. I always get a fatal error. The jvm report A fatal error C [libstdc++.so.6+0x64d24] std::_Rb_tree_rotate_left(std::_Rb_tree_node_base*, std::_Rb_tree_node_base*&)+0x4
