Xiaoyu Yao commented on HADOOP-12358:
-------------------------------------
bq. There's also some danger of client OOMs when trying to delete a large
directory, since getContentSummary is not using the iterator-based listing.
That's an issue we can fix in a different JIRA though.
If the client OOM because of deleting large directory, make it OOM upon
getContentSummary can actually help avoiding an inconsistent (half completed)
deletion states.
> 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.
