As MapR is implemented in C++ most of the calls go through JNI I believe from Java code. If we have lot of JNI calls in system there will be an overhead compared to normal hadoop calls, I would like to run this experiment and see what is the overhead involved if any ones has done this experiment please post a pointer to it.
