ParseException：u“ \下一个输入'/'，期望{'SELECT'，'FROM'，'ADD'，

Question

我试图从目录中读取头文件和相应的csv，而将csv写入pyspark dataframe会引发错误

  

ParseException：u“ \下一个输入'/'，期望{'SELECT'，'FROM'，   'ADD'，IDENTIFIER，BACKQUOTED_IDENTIFIER}（第1行，位置0）\ n \ n == SQL   == \ n / persistent / 4G / filtered_week1 / cell_res \ n ^^^ \ n“

我的代码附在这里：

请让我知道我在这里做错什么了吗

from pyspark.sql import SparkSession
conf = spark.sparkContext._conf.setAll([('spark.executor.memory', '8g'), 
                                        ('spark.executor.cores', '2'), 
                                        ('spark.cores.max', '10'), 
                                        ('spark.driver.memory','8g')])
spark = SparkSession.builder\
                    .config(conf=conf)\
                    .appName("Mergecsv mbnl")\
                    .getOrCreate()

#outfile = "/persistent/4G/week1_15Feb/Untitled Folder"
csv_seperator=','
header= glob.glob(indir + "/*.header")
all_files = glob.glob(indir+ "/*.csv")
        for filename in all_files:
         for head in header:
            x= head.split('.sql')[0]
            if x in filename:
                df1=spark.read.format("csv").option("header", "false").schema(x).load(filename)
                df1.take(1)`
