How to accelerate reading json file?

[Gavin Yue]

I am trying to read json files following the example:

val path = "examples/src/main/resources/jsonfile"val people =
sqlContext.read.json(path)

I have 1 Tb size files in the path.  It took 1.2 hours to finish the
reading to infer the schema.

But I already know the schema. Could I make this process short?

Thanks a lot.
