I'm trying to process a bunch of large json log files with spark, but it fails every time with `scala.MatchError`, Whether I give it schema or not.
I just want to skip lines that does not match schema, but I can't find how in docs of spark. I know write a json parser and map it to json file RDD can get things done, but I want to use `sqlContext.read.schema(schema).json(fileNames).selectExpr(...)` because it's much easier to maintain. thanks
