Hi, Seems this just prevents writers from leaving partial data in a destination dir when jobs fail. In the previous versions of Spark, there was a way to directly write data in a destination though, Spark v2.0+ has no way to do that because of the critial issue on S3 (See: SPARK-10063). //

Re: spark 2.0.0 - when saving a model to S3 spark creates temporary files. Why?
