SparkContext' has no attribute 'builder error

Question

我正在尝试从 pyspark 的数据框中注册模板。代码：

from pyspark.sql import SQLContext
from pyspark import SparkContext
sc = SparkContext.builder.appName("Python Spark").getOrCreate()
sqlCtx = SQLContext()
data = sqlCtx.read.csv("D:/Customers_v01.csv", header=True, inferSchema=True)
data.registerTempTable("data")
spark.sql("SELECT * from data").show()

但这是抛出错误，因为 AttributeError: type object 'SparkContext' has no attribute 'builder'.

数据看起来像

CM,503004,(d$όνυ$F|'.h*Λ!ψμ=(.ξ;      ,.ʽ|!3-2-704              ,.ʽ/8μAθr                    ,(d$όνυ<<*έθr                ,C51,CN-511450

我是不是漏掉了什么。请帮忙

You need to use this way.

from pyspark.sql import SparkSession

spark = SparkSession \
     .builder \
     .appName("Python Spark SQL basic example") \
     .getOrCreate()

创建 spark 会话后，您可以通过这种方式读取 csv。

data = spark.read.csv("D:/Customers_v01.csv", header=True, inferSchema=True, encoding='ISO-8859-1')
