Create Dataframe from a single String in Java

[martin]

Hello,

I am struggling with a task that should be super simple: I would like to 
create a Spark DF of Type Dataset<Row> with one column from a single 
String (or from a one-element List of Strings). The column header should 
be "text".

SparkContext.parallelize() does not work, because it returns RDD<T> and 
not Dataset<Row> and it takes a "ClassTag" as 3rd parameter.

I am able to convert a List of Strings to JavaRDD<Row> using this:
    JavaSparkContext javaSparkContext = new 
JavaSparkContext(sparkContext);

    JavaRDD<String> javaRdd = javaSparkContext.parallelize(textList);

But then I am stuck with this javaRDD. Besides, it seems overly complex 
having to create an intermediate representation.

There is also this SO post with a solution in Scala that I have not been 
able to convert to Java, because the APIs differ:

https://stackoverflow.com/questions/44028677/how-to-create-a-dataframe-from-a-string

Basically, what I am looking for is something simple like:

    Dataset<Row> myData = sparkSession.createDataFrame(textList, 
"text");

Any hints? Thanks a lot.

Cheers,

Martin
