------------------------------------
Thanks [~szetszwo] for review! I think the delete operation is unsafe when
running in production environment. Hence, i use move the path to trash by
default. Recently, we have a case: somebody use *distcp* and and set the target
path argument to the wrong place with delete option,it delete all files from
source path. May be we can keep the same behavior with *Delete.class* of the
*FsShell*, when the trash is enable, try to move the file the trash first, and
only delete them when the trash is unable or given the *skipTrash* option?
What do you think?
> Distcp should move the path to trash when delete missing path from source

> For now, when we use the *distcp* with the delete option, the path will be
> deleted when missing in the source. We should add the option *skipTrash* to
> control the behavior. if *skipTrash* missing, we will move the path to the
> trash first rather than delete them directly.
