Hello Spark users, Does anyone know if there is a way to generate the Scala code for a complex structure just from the output of dataframe.printSchema?
I have to analyse a significant volume of data and want to explicitly set the schema(s) to avoid having to read my (compressed) JSON files multiple times. What I am doing so far is to read a few files, print the schema, and manually write the code to define the corresponding StructType: tedious and error-prone. I'm sure there is a much better way, but can't find anything about it. Pointers anyone?
