从pyspark.sql.types中的
导入StructType 从pyspark.sql.types导入StructField 从pyspark.sql.types导入StringType

sc = SparkContext（conf = SparkConf（）。setAppName（“ Rec_Stream”）。setMaster（“ local [2]”）。set（“ spark.driver.allowMultipleContexts”，“ true”）） sc.setLogLevel（“ WARN”） ssc = StreamingContext（sc，10）

lines_RDD = ssc.socketTextStream（“ localhost”，17020）

data_RDD = lines_RDD.flatMap（lambda line：line.split（'，'）） data_RDD.pprint（）

ssc.start（）
ssc.awaitTermination（）

我想将data_RDD转换为Dataframe，其想法是检查RDD中的值，然后执行适当的操作。

请帮助我！
