Thanks Nathan for your info and effort. I really appreciate it.
Also, I posted the same question on Stackoverflow: http://stackoverflow.com/questions/41969300/java-math-bigdecimal-to-avro-avdl-file, looks like we're not alone. Feel free to share your updates below that question as well to benefit more developers.
