    Description

      Spark currently can only parse JSON files that are JSON lines, i.e. each record has an entire line and records are separated by new line. In reality, a lot of users want to use Spark to parse actual JSON files, and are surprised to learn that it doesn't do that.

      We can introduce a new mode (wholeJsonFile?) in which we don't split the files, and rather stream through them to parse the JSON files.
