> This issue aims to allow a running application to temporarily give back its resources without being killed. Executors are drained gracefully with no loss of in-progress task work or shuffle output, and the application can be resumed later without recomputing the shuffle output already written. Cached blocks are not preserved and are recomputed after resuming.
> This takes effect only when *spark.decommission.enabled* is true, the shuffle data is kept outside the executors (through either *spark.shuffle.service.enabled* or a
> ShuffleDataIO with reliable storage), and the cluster manager can hold executors: Standalone, YARN, and Kubernetes (with the default "direct" allocator).
