16. def expandedSchema(sc: SparkContext, srdd: DataFrame): Seq[(Seq[Int], StructField, Byte)]

    

    Returns expanded schema

    Returns expanded schema

    • schema is represented as list of types and its position inside row
    • all arrays are expanded into columns based on the longest one
    • all vectors are expanded into columns

    sc

    actual Spark context

    srdd

    schema-based RDD

    returns

    list of types with their positions
