具体情况:将pandas中的DF转化为spark中的DF时报错,报错内容如下: spark_df = spark.createDataFrame(target_users) 报错->>Can not merge type <class 'pyspark.sql.types.DoubleType'> and <class 'pyspark.sql.types.StringType'> 根本原因:并非数据类型不匹配,而是数据中存在空值,将空值进行填充后成功创建。
一、问题描述 将pandas的df转为spark的df时,spark.createDataFrame()报错如下: TypeError: field id: Can not merge type <class 'pyspark.sql.types.StringType'> and <class 'pyspark.sql.types.LongType'> 1. 二、 解决方法 是因为数据存在空值,需要将空值替换为空字符串。 pandas_id = pandas_id.replace...
