> As we discussed in HDFS-11102, double confirmation does not seem to be a graceful solution
for users. Deleting files in .Trash accidentally is still an issue though. The behaviour of
users I'm worried about is {{rm}} ing something in .Trash (without explicitly understanding
that those files will not be recoverable). This is in contrast to {{rm}} ing something with
"-skipTrash" option (That's a very purposeful action).
> So it is not the same case as HADOOP-12358. The solution is throwing an exception and
remind user to add "-trash" option to delete dirs in trash for safely:
> {code}
> Can not delete somehing trash directly! Please add "-trash" or "-T" in "rm" command to
do that.
> {code}
