Pyspark - 无法在hadoop二进制路径中找到winutils二进制文件

时间：2018-06-01 06:56:55

标签： python apache-spark pyspark

我正在尝试将pyspark与python 2.7（Pycharm IDE）集成。我需要运行一些巨大的文本文件。

所以这就是我在做的事。

下载Spark（2.3.0-bin-hadoop-2.7）并解压缩 安装JDK

然后我试图运行这个脚本

spark_home = os.environ.get（'SPARK_HOME'，无） os.environ [“SPARK_HOME”] =“C：\ spark-2.3.0-bin-hadoop2.7” 进口pyspark 来自pyspark导入SparkContext，SparkConf 来自pyspark.sql导入SparkSession 

conf = SparkConf()
sc = SparkContext(conf=conf)
spark = SparkSession.builder.config(conf=conf).getOrCreate() 
import pandas as pd
ip = spark.read.format("csv").option("inferSchema","true").option("header","true").load(r"D:\some file.csv")

Pycharm说没有找到名为Pyspark的模块。

我通过添加内容根并指向安装它的文件夹来解决这个问题。

但问题是每次我重新打开pycharm时，我都要添加内容根。我该如何解决这个问题？

接下来，当我设法运行脚本时，它会引发以下错误。

我做了一些研究并推断它是由于spark文件夹中缺少winutils.exe引起的。我下载并将其放入火花箱。这个错误仍在继续。我该如何解决这个问题？

2 个答案:

答案 0 :(得分：0)

查看this git book

  

从https://github.com/steveloughran/winutils存储库下载winutils.exe二进制文件。

     

请注意       您应该选择编译Spark分发版的Hadoop版本，例如：使用hadoop-2.7.1 for Spark 2（这里是winutils.exe二进制文件的直接链接）。

     

将winutils.exe二进制文件保存到您选择的目录中，例如C：\的hadoop \ BIN

答案 1 :(得分：0)

Spark通常需要完整的Hadoop安装。但是，如果您不打算使用Hadoop执行distrubite计算，那么winutils.exe是一个创建的工具，例如，因为您只是在Windows上本地测试Spark。

按WIN + PAUSE，转到高级设置和环境变量。

将新环境变量HADOOP_HOME设置为您选择的目录。我推荐C:\winutils而不是hadoop，因为这不是一个完整的hadoop安装。

在其中创建目录bin，将文件winutils.exe放在bin。

中

编辑路径，将%HADOOP_HOME%\附加到其中。

现在pyspark应该可以正常工作，只要你在本地工作而没有分配功能。
