Asking for help, clarification, or responding to other answers. The schema inference process is not as expensive as it is for CSV and JSON, since the Parquet reader needs to process only the small-sized meta-data files to implicitly infer the schema rather than the whole file. ignore Ignores write operation when the file already exists, alternatively you can use SaveMode.Ignore. you can use more than one character for delimiter in RDD, you can transform the RDD to DataFrame (if you want), using toDF() function, and do not forget to specify the schema if you want to do that, pageId]|[page]|[Position]|[sysId]|[carId But in this way i have create schema,so for example if i have text file that has 100 columns i have to write 100 times this .
