Scala Spark将字符串写入文件

Question

我正在使用一个Spark集群，我想将一个字符串写入文件并使用Scala将其保存到主节点中，我查看了本主题并尝试了一些建议，但是找不到保存的文件

Answer 1

You would just need to call collect on the RDD to bring the collection back to the driver. Then you can write it to the file system on the driver.

Although it would be recommended to write it in a parallelized fashion for performance.
