【问题描述】：
我在将 spark 数据帧写入 csv 和 parquet 时出错。我已经尝试安装winutil，但仍然没有解决错误。
我的代码
INVALID_IMEI <- c("012345678901230","000000000000000")
setwd("D:/Revas/Jatim Old")
fileList <- list.files()
cdrSchema <- structType(structField("date","string"),
structField("time","string"),
structField("a_number","string"),
structField("b_number", "string"),
structField("duration","integer"),
structField("lac_cid","string"),
structField("imei","string"))
file <- fileList[1]
filePath <- paste0("D:/Revas/Jatim Old/",file)
dataset <- read.df(filePath, header="false",source="csv",delimiter="|",schema=cdrSchema)
dataset <- filter(dataset, ifelse(dataset$imei %in% INVALID_IMEI,FALSE,TRUE))
dataset <- filter(dataset, ifelse(isnan(dataset$imei),FALSE,TRUE))
dataset <- filter(dataset, ifelse(isNull(dataset$imei),FALSE,TRUE))
要导出数据框，我尝试以下代码
write.df(dataset, "D:/spark/dataset",mode="overwrite")
write.parquet(dataset, "D:/spark/dataset",mode="overwrite")
我得到以下错误
Error: Error in save : org.apache.spark.SparkException: Job aborted.
