I guess it would be nicer if the title has the form such as |
| * | ||
| * @param jsonRDD input RDD with one JSON object per record | ||
| * @since 1.4.0 | ||
| * @since 1.4.0* |

It seems there is a typo here, *.

| def complexFieldAndType1: Dataset[String] = | ||
| sqlContext.createDataset( |

I guess it is preferred to use spark rather than sqlContext..

I just fetched this PR and run tests. It seems BTW, I guess it is arguable to add a new API. For me, I feel it is a bit questionable to add this API because there is already rdd one, I guess APIs would not be added only for consistency. Maybe I think we should wait for a committer's call. |

@HyukjinKwon this change in input parameter relates to #13300. There was a request there to treat Dataset[String] as a preferred input to RDD[String]. |

@HyukjinKwon all the JsonSuite tests pass for me on my laptop - would it be feasible to get this reviewed again? |
