pyspark dataframe saveAsText

To save a PySpark DataFrame as a text file, you can use the `write` method with the `text` format option. Here's an example:

df.write.format("text").save("path/to/save/file")

In this example, `df` is your PySpark DataFrame, `"text"` is the format option indicating that you want to save it as a text file, and `"path/to/save/file"` is the path where you want to save the file.

Note that this will create a directory with multiple text files, one for each partition of the DataFrame. If you want to save the entire DataFrame as a single text file, you can use the `coalesce` method to reduce the number of partitions to one before saving:

df.coalesce(1).write.format("text").save("path/to/save/file")
