For me inference is not an issue as compared to persistence.
Imagine a Streaming application where the input is JSON whose format can
vary from row to row and whose format I cannot pre-determine.
I can use `sqlContext.jsonRDD` , but once I have the `SchemaRDD`, there is
no way for me to update the
You can resort to |SQLContext.jsonFile(path: String, samplingRate:
Double)| and set |samplingRate| to 1.0, so that all the columns can be
inferred.
You can also use |SQLContext.applySchema| to specify your own schema
(which is a |StructType|).
