  11. def getCachedDataFrame(df: DataFrame): DataFrame

    Create a new cached copy of a DataFrame.

    Create a new cached copy of a DataFrame. For iterative DataFrame-based algorithms.

    WARNING: This is NOT the same as DataFrame.cache(). The original DataFrame will NOT be cached.

    This is a workaround for SPARK-13346, which makes it difficult to use DataFrames in iterative algorithms. This workaround converts the DataFrame to an RDD, caches the RDD, and creates a new DataFrame. This is important for avoiding the creation of extremely complex DataFrame query plans when using DataFrames in iterative algorithms.
