> Current schema inferance for local python collections halts as soon as there are no NullTypes. This is different than when we specify a sampling ratio of 1.0 on a distributed collection. This could result in incomplete schema information.
> Repro:
> {code}
> input = [{"a": 1}, {"b": "coffee"}]
> df = sqlContext.createDataFrame(input)
> print df.schema
> {code}
> Discovered while looking at SPARK-2870
