我将csv文件加载到pyspark中,如下所示(在pyspark shell中)：

>>> from pyspark.sql import SQLContext
>>> sqlContext = SQLContext(sc)
>>> df = sqlContext.read.format('com.databricks.spark.csv').options(header='true').load('data.csv')

但我收到这个错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'SQLContext' object has no attribute 'read'
>>> 

我正在使用spark 1.3.1,我正在尝试使用spark-csv

解决方法:

您正在尝试使用Spark 1.4语法.

对于Spark 1.3

from pyspark.sql import SQLContext
sqlContext = SQLContext(sc)

df = sqlContext.load(source="com.databricks.spark.csv", header="true", path = "cars.csv")
df.select("year", "model").save("newcars.csv", "com.databricks.spark.csv")
