read_json(path: str, lines: bool = True, index_col: Union[str, List[str], None] = None, **options: Any) → pyspark.pandas.frame.DataFrame将JSON 字符串转换为 DataFrame。参数: path:string 文件路径 lines:布尔值,默认为真 将文件作为每行的 json 对象读取。现在应该始终为 True。 index_col...
Look wise JSON is similar to aPython dictionarywhere JSON keys must be string-type objects with a double-quoted and values can be any datatype such as string, integer, nested JSON, a list, a tuple, or even another dictionary. In order to work with JSON string or a file, Python provide...
Apache Spark can also be used to process or read simple to complex nested XML files into Spark DataFrame and writing it back to XML using DatabricksSpark XML API(spark-xml) library. In this article, I will explain how to read XML file with several options using the Scala example. Advertise...
Notebook Kernels also support other features like Files in Repo to build libraries within your repo, _sqldf to expose results of SQL cells to Python/Pyspark, %run to run other notebooks inline with the current notebook and also dbutils.notebook.run(). However, there are some known limitatio...
