python中spark字数计算程序出错

首先，我是python和spark的新手，所以这个问题可能有点傻。在这里：
我试着用python运行一个单词计数spark程序。程序如下：

import sys
from pyspark import SparkConf, SparkContext

conf = SparkConf()
sc = SparkContext(conf=conf)

text_file = sc.textFile(sys.argv[1])

def Map_Function(word):
    return(word,1)
def Reduce_Function(count_1, count_2):
    return count_1+count_2
counts = textFile.flatMap(lambda line:
line.split(" ")) \
    .map(Map_Function) \
    .refuceByKey(Reduce_Function)
counts.saveAsTextFile(sys.argv[1] + "_result")

我试图在windows anaconda提示符下用命令>python sprk.py mytextfile.txt（sprk.py是我保存程序的文件，mytextfile.txt是我想从中读取的文本文件-它与sprk.py保存在同一个文件夹中）运行此程序，但出现了一个很长的错误：

[ERROR] 2019-02-23 10:10:35 WARN  NativeCodeLoader:62 - Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).
