-------------------------------------
Thanks [~aw] for the feedback. I really appreciate it. Some earlier ones
regarding compatibility have included in my 1st patch as [~andrew.wang] has
mentioned.
bq. Between snapshots and trash, there are plenty of ways to protect against
this situation.
What if these are not configured or not configured correctly by ops and used
correctly by users (-skipTrash)?
bq. You can't protect the user from making every single mistake without turning
the system into a 'nanny system' that makes you verify every single thing.
We don't want to build a 'nanny system'. The purpose of this JIRA is to
protect/warn against *bulk deletion* only on *misconfigured* cluster (without
trash/snapshot) or *misuse* (trash is skipped), which is hard to recover.
> FSShell should prompt before deleting directories bigger than a configured

> We have seen many cases with customers deleting data inadvertently with
> -skipTrash. The FSShell should prompt user if the size of the data or the
> number of files being deleted is bigger than a threshold even though
> -skipTrash is being used.
