yucai commented on issue #10225: [SPARK-12196][Core] Store/retrieve blocks from different speed storage devices by hierarchical way URL: https://github.com/apache/spark/pull/10225#issuecomment-478906306 @tobegit3hub, one alternative way could be using full SSDs when shuffle, while storing data on HDDs(maybe remotely), so you don't need so many SSD. Is it affordable and enough for you?
