Apache spark 如何在客户机上运行spark

我正在尝试在Thread客户端上运行pyspark，不确定原因是什么，并且无法正确解释日志

import sys
from pyspark.sql import SparkSession
from pyspark import SparkContext, SparkConf
conf = SparkConf()
conf.setMaster('yarn-client')
conf.setAppName('SPARK APP')
sc = SparkContext(conf=conf)
# sc= SparkContext.getOrCreate()
# sc.stop()

def mod(x):
    import numpy as np
    return (x, np.mod(x, 2))

rdd = sc.parallelize(range(1000)).map(mod).take(10)
print (rdd)

代码不断抛出以下异常

当我给用户该路径的所有权和权限时，问题就解决了

chown sw /home/sw/.sparkStaging/
