Junjeng, it worth a try to start your spark local with hadoop.dll/winutils.exe etc hadoop windows support package in HADOOP_HOME, if you didn’t do that yet.

I find some documents about enable snappy on hadoop. If I want to use snappy with spark, do I need to config spark as hadoop or have some easy way to access it?
