--------------------------------------
Why would you delete the folder intentionally?
> If folders managed by DiskBlockManager are deleted manually, shell throws
> FileNotFoundException

> # In spark shell
> # Run a join query, which writes some data to folders managed by
> DiskBlockManager.
> # Delete some of the folders,
