Harsh J commented on HDFS-2740:
-------------------------------

[~eli] - The FsShell does log out that the file was moved to trash and not completely removed. If we can solve this with more info/doc efforts, am up for doing that.

I do think a lot of them miss out on the trash feature until they run into a situation that makes them search if there is one.

Stuff we can document more explicitly about, to help:
- How do I disable Trash?
- How do I clear out Trash?
- How do I force-delete a file (skipping trash)?
- How do I tweak the checkpoint periods?

And maybe some dev documentation on trash policies, as I think that is now pluggable (evolving API)?

> Currently trash is disabled out of box. I do not think it'd be of high surprise to anyone (but surely a relief when *hit happens) to have trash enabled by default, with the usually recommended periods of 1-day.
> Thoughts?
