> DataFrameRead.json(path) compatibility broken with Spark 1.6

> Key: SPARK-16009

> {{DataFrameRead.json(string)}} was removed as it was covered by
> {{DataFrameRead.json(string-varargs) }}. But this breaks compilation where
> the compiler needs a method with single arg. Example
> {code}
> Option(path).map(spark.read.json)
> {code}
> This works in 1.6 and does not compile in 2.0.
