我正在使用以下代碼-
df.repartition(1).write.format('com.databricks.spark.csv').mode('overwrite').save(output_path,quote='',escape='\"', sep='|', header='True', nullValue=None)
uj5u.com熱心網友回復：
你把escape論證和quote論證混淆了：
df.repartition(1).write.format('com.databricks.spark.csv').mode('overwrite').save(output_path, quote='\"', sep='|', header='True', nullValue=None)
這應該有效。便捷鏈接：https : //spark.rstudio.com/reference/spark_write_csv.html
